DESCRIPTION:Title: Multiphase models of living tissues and the Hele-Shaw limit
\nby Benoit Perthame (Sorbonne University\, France) as part of Seminar In
the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nThe mechanical m
odeling of living tissues has attracted much attention in the last decade
. Applications include tissue repair and growth models of solid tumors. T
hese models contain several levels of complexity\, both in terms of the bi
ological and mechanical effects\, and therefore in their mathematical desc
ription. Multiphase models describe the dynamics of several types of cells
\, liquid\, fibers (extra-cellular matrix) and both compressible and incom
pressible models are used in the literature.\n\nIn this talk I shall discu
ss the analysis of multiphase models based on Darcy's assumption. The comp
actness issue leads us to use Aronson-Benilan estimate and to build new va
riants. I shall also discuss the incompressible limit in special cases and
the associated free boundary problem.\n

DESCRIPTION:Title: The thresholding scheme for mean curvature flow and De Giorgi's id
eas for gradient flows\nby Felix Otto (Max Planck Institute for Mathem
atics in the Sciences\, Leipzig\, Germany) as part of Seminar In the Analy
sis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nFlow of interfaces by mea
n curvature\, in its multi-phase version\,\nwas first formulated in the co
ntext of grain growth in polycrystalline materials. \nThe computationally
efficient and very popular thresholding scheme\nfor mean curvature flow by
Osher et. al. can be naturally extended \nto such a multi-phase situation
\, even for surface tensions that depend on \nthe lattice mismatch between
the adjacent grains.\n\nThis extension relies on the gradient flow struct
ure of mean curvature flow\,\nand the interpretation of the thresholding s
cheme\nas a corresponding "minimizing movements'' scheme\, that is\, a seq
uence of variational problems\nnaturally attached to the implicit time dis
cretization of a gradient flow.\n\nThis interpretation also allows for a (
conditional) convergence proof based on De Giorgi's ideas\nfor gradient fl
ows in metric spaces. The approach is similar to\nthe convergence proof fo
r the minimizing movement scheme by Almgren\, Taylor and Wang\,\nas given
by Luckhaus et. al. \n\nThis is joint work with S. Esedoglu and T. Laux.\n

DESCRIPTION:Title: Generic regularity in obstacle problems\nby Alessio Figalli (E
TH Zurich\, Switzerland) as part of Seminar In the Analysis and Methods of
PDE (SIAM PDE)\n\n\nAbstract\nThe classical obstacle problem consists of
finding the equilibrium position of an elastic membrane whose boundary is
held fixed and constrained to lie above a given obstacle. By classical res
ults of Caffarelli\, the free boundary is smooth outside a set of singular
points. Explicit examples show that the singular set could be in general
(n-1)-dimensional — that is\, as large as the regular set. In a recent p
aper with Ros-Oton and Serra we show that\, generically\, the singular set
has codimension 3 inside the free boundary\, solving a conjecture of Scha
effer in dimension $n\\leq 4$. This talk aims to give an overview of these
results.\n

DESCRIPTION:Title: Finite dimensional approximations of Hamilton-Jacobi-Bellman equat
ions in spaces of probability measures. (Featured Article in SIAM Journal
on Mathematical Analysis)\nby Andrzej Swiech (Georgia Tech\, USA) as p
art of Seminar In the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract
\nWe will discuss how certain Hamilton-Jacobi-Bellman (HJB) equations in s
paces of probability measures can be approximated by finite dimensional eq
uations. The most interesting cases are convergence of viscosity solutions
of HJB equations corresponding either to deterministic optimal control pr
oblems for systems of $n$ particles or to stochastic optimal control probl
ems for systems of $n$ particles with a common noise\, to the viscosity so
lution of a limiting HJB equation in the space of probability measures. Th
e limiting HJB equation is interpreted in its ``lifted" form in a Hilbert
space\, which has a unique viscosity solution. When the Hamiltonian is con
vex in the gradient variable and equations are of first order\, it can be
proved that the viscosity solutions of the finite dimensional problems con
verge to the value function of a variational problem in $\\mathcal{P}_2(\\
R^d)$ thus providing a representation formula for the solution of the limi
ting first order HJB equation. The talk will also contain an overview of e
xisting works and various approaches to partial differential equations in
abstract spaces\, including spaces of probability measures and Hilbert spa
ces. The talk is based on a joint work with W. Gangbo and S. Mayorga.\n\nF

DESCRIPTION:Title: Auxiliary functionals: a path to solving the problem of turbulence
\nby Sergei Chernyshenko (Imperial College London\, UK) as part of Sem
inar In the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nThe prob
lem of turbulence is the greatest unsolved problem of classical fluid dyna
mics. It is quite old. Similarly\, the problem of optimizing over the con
e of nonnegative polynomials was long believed to be too hard\,\nuntil at
the start of the millennium a breakthrough paved a way by linking it\, thr
ough sum-of-squares polynomial optimisation\, to semidefinite programming.
And only a few years ago\, auxiliary functionals were proposed with an \n
ultimate goal of applying the fruits of this breakthrough to solving the p
roblem of turbulence. The essence of these ideas is remarkably simple. The
talk will cover the basics\, and then a few questions will be reviewed de
eper\, including applications to systems of equations with energy-conservi
ng quadratic nonlinearities\, such as the Kuramoto–Sivashinsky and the N
avier-Stokes equations.\n

DESCRIPTION:Title: Gaussian lower bounds for the Boltzmann equation without cut-off<
/a>\nby Luis Silvestre (University of Chicago) as part of Seminar In the A
nalysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nThe Boltzmann equatio
n models the evolution of densities of particles in a gas. Its global well
posedness is a major open problem\, facing comparable difficulties as sim
ilar questions for equations in fluids. With current techniques\, we canno
t rule out the possibility of a spontaneous emergence of a singularity in
the form of infinite mass or energy density concentrating at some point in
space. This work is part of a series of a priori estimates for the inhomo
geneous non-cutoff Boltzmann equation that are conditional to bounds on ma
croscopic quantities. We establish a Gaussian lower bound for solutions to
the Boltzmann equation without cutoff\, in the case of hard and moderatel
y soft potentials\, with spatial periodic conditions\, and under the sole
assumption that hydrodynamic quantities (local mass\, local energy and loc
al entropy density) remain bounded. In the talk\, we will discuss how this
lower bound fits in the larger program of conditional estimates.\n

DESCRIPTION:Title: Analytical aspects of emergent dynamics in systems of collective
behavior\nby Roman Shvydkoy (University of Illinois\, Chicago) as part
of Seminar In the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nO
ne of the challenging problems in the field of collective behavior is to u
nderstand global emergent phenomena arising from purely local communicatio
n between agents. In the context of alignment dynamics examples of such gl
obal phenomena include flock formations\, reaching consensus of opinions
\, emergence of leaders\, etc. For models based on purely local interacti
ons the assumption of graph-\, chain-\, or hydrodynamic connectivity of th
e flock is often necessary\, but not always guaranteed\, to ensure collect
ive outcome. In this talk we will give an overview of the subject and hig
hlight two new approaches to alignment dynamics in disconnected or weakly
connected flocks. One is based on a topological fractional diffusion that
resembles the closest neighbor rule originating in various empirical studi
es\, and another based on the use of random fluctuations and the hypocoerc
ivity property for the resulting kinetic Fokker-Planck-Alignment equation.

Theodore Drivas (Stony Brook University) as part of Seminar In the Analysi

f one-dimensional compressible fluid equations\; Navier-Stokes models with
local dissipation in which the viscosity depends degenerately on the dens
ity and nonlocal models for collective dynamics which exhibit flocking beh
avior. For the local models\, we prove large data global regularity for a
class of equations covering viscous shallow water. Another result proves a
conjecture of Peter Constantin on singularity formation for a model descr
ibing slender axisymmetric fluid jets. For the non-local models\, we esta
blish a continuation criterion which says that smooth solutions exist so l
ong as no vacuum states form. The method of proof involves introducing a
hierarchy of entropies to control the solution in terms of the minimum den
sity. We also show that any weak solutions which obeying an entropy inequ
ality exhibit flocking. This reports on joint work with P. Constantin\, H

DESCRIPTION:Title: Symmetry and uniqueness via a variational approach\nby Yao Ya
o (National University of Singapore) as part of Seminar In the Analysis an
d Methods of PDE (SIAM PDE)\n\n\nAbstract\nFor some nonlocal PDEs\, their
steady states can be seen as critical points of some associated energy fun
ctional. Therefore\, if one can construct perturbations around a function
such that the energy decreases to first order along the perturbation\, thi
s function cannot be a steady state. In this talk\, I will discuss how thi
s simple variational approach has led to some recent progress in the follo
wing equations\, where the key is to carefully construct a suitable pertur
bation. \n\nI will start with the aggregation-diffusion equation\, which i
s a nonlocal PDE driven by two competing effects: nonlinear diffusion and
long-range attraction. We show that all steady states are radially symmetr
ic up to a translation (joint with Carrillo\, Hittmeir and Volzone)\, and
give some criteria on the uniqueness/non-uniqueness of steady states withi
n the radial class (joint with Delgadino and Yan). I will also discuss the
2D Euler equation\, where we aim to understand under what condition must
a stationary/uniformly-rotating solution be radially symmetric. Using a va
riational approach\, we settle some open questions on the radial symmetry
of rotating patches\, and also show that any smooth stationary solution wi
th compactly supported and nonnegative vorticity must be radial (joint wit
h Gómez-Serrano\, Park and Shi).\n

nlinear dispersive PDE\nby Andrea Nahmod (University of Massachusetts
Amherst -- USA) as part of Seminar In the Analysis and Methods of PDE (SIA
M PDE)\n\n\nAbstract\nIn groundbreaking work\, Bourgain ’96 put forward
a random data theory to study the existence of strong solutions on the sta
tistical ensemble of Gibbs measures associated to dispersive equations. De
spite numerous follow-up works to those of Bourgain’s\, fundamental ques
tions remained open. How does a given initial random data get transported
by a nonlinear flow ? If it is Gaussian initially\, how does this Gaussia
nity propagate? What is the description of the solution beyond the linear
evolution?\n\nIn recent work\, joint with Yu Deng and Haitian Yue\, we dev
eloped the theory of random tensors\, a powerful new framework which allow
s us to unravel the propagation of randomness under the NLS flow beyond th
e linear evolution of random data\, and answer these questions in an optim
al range relative to what we define as the probabilistic scaling. In part
icular\, we establish the invariance of Gibbs measures for 2D NLS and 3D H
artree NLS equations using the method of random averaging operators\, a fi
rst order approximation to the full random tensor theory. \n\nIn this talk
we will describe these results\, and explain the ideas behind them. We co
nclude with some open problems and within this context present new work\,
joint with Bjoern Bringmann\, Yu Deng and Haitian Yue establishing the i
nvariance of the 3D Gibbs measure under the flow of the nonlinear wave equ
ation.\n\nBio Andrea R. Nahmod is Professor of Mathematics at the Universi

ar Fourier and harmonic analysis\, and the theory of partial differential
equations. Some of her recent work aims at gaining a quantitative understa

spersive PDE. Nahmod is a Fellow of the American Mathematical Society\; a

A. Kiselev\, Changhui Tan \n\nThe question of how roots of polynomials mo
ve under differentiation is classical. Contributions to this subject have
been made by Gauss\, Lucas\, Marcel Riesz\, Polya and many others. In 2018
\, Stefan Steinerberger derived formally a PDE that should describe the dy
namics of roots under differentiation in certain situations. The PDE in qu
estion is of hydrodynamic type and bears a striking resemblance to the mod
els used in mathematical biology to describe collective behavior and flock
ing of various species - such as fish\, birds or ants. The equation is cri
tical\, but due to strongly nonlinear form of its coefficients\, proving g
lobal regularity for its solutions is harder than for equations such as Bu
rgers\, SQG or Euler alignment model. I will discuss joint work with Chang
hui Tan in which we establish global regularity of Steinerberger's equatio
n and make a rigorous connection between its solutions and evolution of ro
ots under differentiation for a class of trigonometric polynomials.\n

will present an overview of the theory of quantitative homogenization (st
ochastic as well as periodic) for elliptic and parabolic equations\, which
has been developed in the last ten years. A particular emphasis will be o
n the idea of "coarse-graining the coefficient field" with applications to
degenerate equations and other situations which require "renormalization\
," including some more recent applications to models in mathematical physi
cs. Time permitting\, I will discuss what I see as some of the most import

he Benjamin-Ono equation is a nonlinear dispersive wave equation in one sp

ow the use of a Lax pair provides a fairly complete picture of the dynamic
s with periodic boundary conditions. I will discuss an explicit formula fo
r the solutions\, global well posedness in sharp regularity\, long time d

n\nFeatured Article Authors: Alberto Bressan\, Sondre T. Galtung and Qing
Su.\n\n\nLiving organisms come in an immense variety of shapes.\nIn many
cases one can expect that\, through natural selection\, a ``best possible"
shape will have evolved. From a mathematical perspective\, it is thus of
interest to understand whether similar geometric shapes can be recovered a
s minimizers of suitable functionals.\n\nAs a step in this direction\, we
consider two functionals measuring the efficiency of roots and branches in
a tree. Namely: \n(i) a ``sunlight functional"\, modeling the total amoun
t of sunlight captured by the leaves of a tree\, and\n(ii) a ``harvest fun
ctional"\, modeling the amount of nutrients collected by the roots.\nThe a
bove functionals must be combined with a ``ramified transportation cost"\,
for transporting nutrients from the roots to the base of the trunk\, or f
rom the base of the trunk to the leaves.\n\nThe talk will address the semi
continuity of these functionals\, and the existence and properties of opti
mal solutions\, in a space of measures.\nOpen problems will also be discus
sed\, including computational issues and how these optimal shapes may depe
nd on various parameters.\n

DESCRIPTION:Title: Effective gaps for time-periodic Hamiltonians modeling Floquet ma
terials\nby Michael Weinstein (Columbia University) as part of Seminar
In the Analysis and Methods of PDE (SIAM PDE)\n\n\nAbstract\nFeatured Art
icle: "Effective gaps in continuous Floquet Hamiltonians"\, SIAM J Math
Analysis 54 #1 2022. \n\nFeatured Article Authors: Amir Sagiv and Micha
el Weinstein\n\n\nFloquet media are a type of material\, in which time-per
iodic forcing is applied to alter the material’s energy transport proper
ties. Examples in classical and quantum physics include (i) applying a tim
e-oscillating electric field to a graphene sheet to influence quantum elec
tronic transport\, and (ii) replacing a periodic array of standard optical
waveguides by an array of helically coiled waveguides to influence the fl
ow of light propagation in the array. The ability to modify energy transpo
rt via time modulation is recognized as having great potential for applica
tions to information transfer\, information processing\, and other applica
tions. \n\nWe discuss Floquet materials governed by a class of parametrica
lly forced Schrödinger equations\, which arises in the above examples: \n
i ψt = Hε (t) ψ\, Hε(t) = H0 + ε W ( ε t \, -i ∇ ).
(1)\n\nThe operator H0 = - Δ + V ( x ) models a graphene-like static m
aterial\; the potential V has the symmetries of a honeycomb tiling of the
plane. The family of self-adjoint operators T ↦ W ( T\, -i ∇ ) is assu
med to be Tper – periodic. \n\nWhile the energy transport of the unforce
d system ( W ≡ 0 ) is governed by the band structure (Floquet-Bloch spec
tral theory) of H0 \, that of the forced system is characterized by the mo
nodromy operator\, the unitary mapping ψ0 ↦ ψ ( ε-1 Tper ) \, and its
associated quasi-energy spectrum. Gaps in the band spectrum and quasi-ene
rgy spectrum\, respectively\, of static and Floquet materials\, play an im
portant role in their transport properties. \n\nThe evolution under Hε (t
) of band-limited Dirac wave-packets (a natural model of physical excitati
ons) is well-approximated on very large time scales by an effective time-p
eriodic Dirac equation\, which has a gap in its quasi-energy spectrum. But
little is known about the nature of the quasi-energy spectrum of (1)\, an
d it is believed that no such quasi-energy gap occurs. \n\nWe explain how
to transfer quasi-energy gap information about the effective Dirac dynamic
s to conclusions about the full Schrödinger dynamics (1). In particular\,
we show that (1) has an effective quasi-energy gap\, an interval of quasi
-energies whose corresponding modes have only a very small spectral projec
tion onto the subspace of band-limited Dirac wave-packets. The notion of e
ffective quasi-energy gap is a physically relevant relaxation of the stric
t notion of quasi-energy spectral gap. Physically\, if a system is tuned t
o drive or measure at momenta and energies near the Dirac point of H0 \, t
hen the resulting modes in the effective quasi-energy gap will only be wea
kly excited and detected. \n\nThis lecture focuses on joint work with Amir
Sagiv (Columbia University) appearing in the article: Effective gaps in c
ontinuous Floquet Hamiltonians\, SIMA 54 #1 2022.\n
