DESCRIPTION:Title: Symmetry in Fourier Analysis – Heisenberg to Stein-We
iss\nby William Beckner (University of Texas at Austin) as part of Geometr
ic and functional inequalities and applications\n\n\nAbstract\nEmbedded sy
mmetry within the Heisenberg group is used to couple geometric insight and
analytic calculation to obtain a new sharp Stein-Weiss inequality with mi
xed homogeneity on the line of duality. SL(2\,R) invariance and Riesz pote
ntials define a natural bridge for encoded information that connects disti
nct geometric structures. Insight for Stein-Weiss integrals is gained from
vortex dynamics\, embedding on hyperbolic space\, and conformal geometry.
The intrinsic character of the Heisenberg group makes it the natural play
ing field on which to explore the laws of symmetry and the interplay betwe
en analysis and geometry on a manifold.\n\nZoom link: https://brown.zoom.u

Andrea Malchiodi (Scuola Normale Superiore) as part of Geometric and funct

oduce a natural concept of “mass” and prove its positivity under the c
ondition that\nthe scalar curvature is positive and in relation to their (
holomorphic) embeddability properties.\nWe apply this result to the CR Yam

ng some counterexamples for “Rossi spheres”.\nThis is joint work with

DESCRIPTION:Title: Stable solutions to semilinear elliptic equations are s
mooth up to dimension 9\nby Xavier Cabre (ICREA and UPC (Barcelona)) as pa
rt of Geometric and functional inequalities and applications\n\n\nAbstract
\nThe regularity of stable solutions to semilinear elliptic PDEs has been
studied since the 1970's. In dimensions 10 and higher\, there exist singul
ar stable energy solutions. In this talk I will describe a recent work in
collaboration with Figalli\, Ros-Oton\, and Serra\, where we prove that st
able solutions are smooth up to the optimal dimension 9. This answers to a
n open problem posed by Brezis in the mid-nineties concerning the regulari
ty of extremal solutions to Gelfand-type problems.\n\nZoom link: https://b

upert Frank (CalTech) as part of Geometric and functional inequalities and
applications\n\n\nAbstract\nWe are interested in a new family of reverse
Hardy–Littlewood–Sobolev inequalities which involve a power law kernel
with positive exponent and a Lebesgue exponent <1. We characterize the ra
nge of parameters for which the inequality holds and present results about
the existence of optimizers. A striking open question is the possibility
of concentration of a minimizing sequence.\n\nThis talk is based on joint

DESCRIPTION:Title: A mean curvature type flow and isoperimetric problem in
warped product spaces\nby Pengfei Guan (McGill University) as part of Geo
metric and functional inequalities and applications\n\n\nAbstract\nWe will
discuss a mean curvature type flow with the goal to solve isoperimetric p
roblem. The flow is induced from the variational properties associated to
conformal Killing fields. Such flow was first introduced in space forms in
a previous joint work with Junfang Li\, where we provided a flow approach
to the classical isoperimetric inequality in space form. Later\, jointly
with Junfang Li and Mu-Tao Wang\, we considered the similar flow in warped
product spaces with general base. Under some natural conditions\, the flo
w preserves the volume of the bounded domain enclosed by a graphical hyper
surface\, and monotonically decreases the hypersurface area. Furthermore\,
the regularity and convergence of the flow can be established\, thereby t
he isoperimetric problem in warped product spaces can be solved. The flow
serves as an interesting way to achieve the optimal solution to the isoper
imetric problem.\n\nZoom link: https://brown.zoom.us/j/99054390401\n

esent a result on the rigidity of local minimizers of the functional $\\in
t \\sigma_2+ \\oint H_2$ among all conformally flat metrics in the Euclide
an (n + 1)-ball. We prove the metric is flat up to a conformal transformat
ion in some (noncritical) dimensions. We also prove the analogous result i
n the critical dimension n + 1 = 4. The main method is Frank-Lieb’s rear
rangement-free argument. If minimizers exist\, this implies a fully nonlin
ear sharp Sobolev trace inequality. I will also discuss a nonsharp Sobolev
trace inequality. This is joint work with Jeffrey Case.\n

Thirring conjectured that the kinetic energy of fermions is not smaller t
han its Thomas-Fermi (semiclassical) approximation\, at least in three or
higher dimensions. I will discuss a rigorous lower bound with the sharp se
miclassical constant and a gradient error term which is normally of lower
order in applications. The proof is based on a microlocal analysis and a
variant of the Berezin-Li-Yau inequality. This approach can be extended t
o derive an improved Lieb-Thirring inequality for interacting systems\, wh
ere the Gagliardo-Nirenberg constant appears in the strong coupling limit.

DESCRIPTION:Title: Stability in Gagliardo-Nirenberg inequalities\nby Jean
Dolbeault (Université Paris-Dauphine) as part of Geometric and functional
inequalities and applications\n\n\nAbstract\nOptimal constants and optima
l functions are known in some functional inequalities. The next question i
s the stability issue: is the difference of the two terms controlling a di
stance to the set of optimal functions ? A famous example is provided by S
obolev's inequalities: in 1991\, G. Bianchi and H. Egnell proved that the
difference of the two terms is bounded from below by a distance to the man
ifold of the Aubin-Talenti functions. They argued by contradiction and gav
e a very elegant although not constructive proof. Since then\, estimating
the stability constant and giving a constructive proof has been a challeng
e. \n\nThis lecture will focus mostly on subcritical inequalities\, for wh
ich explicit constants can be provided. The main tool is based on entropy
methods and nonlinear flows. Proving stability amounts to establish\, unde
r some constraints\, a version of the entropy - entropy production inequal
ity with an improved constant. In simple cases\, for instance on the spher
e\, rather explicit results have been obtained by the « carré du champ
» method introduced by D. Bakry and M. Emery. In the Euclidean space\, re
sults based on constructive regularity estimates for the solutions of the
nonlinear flow and corresponding to a joint research project with Matteo B
