DESCRIPTION:Title: Sharp stability for the interaction energy\nby Xukai Yan (Okla
homa State University) as part of VCU ALPS (Analysis\, Logic\, and Physics
Seminar)\n\n\nAbstract\nFor a nonnegative density f and radially decreasi
ng interaction potential W\, the interaction energy is given by E[f]= \\i
nt f(x)f(y)W(x-y) dxdy. The celebrated Riesz rearrangement inequality say
s that the interaction energy satisfies E[f] \\le E[f^*]\, where f^* is th
e radially decreasing rearrangement of f. In this talk\, I will discuss th
e quantitative estimate of this inequality. I will first make an introduct
ion about the problem and describe some previous results about the stabili
ty estimate for characteristic functions. I will then present a recent wo
rk with Yao Yao\, where we establish the stability estimate for general de
nsities.\n

DESCRIPTION:Title: 3D smectic liquid crystals\nby Michael Novack (The University
of Texas\, Austin) as part of VCU ALPS (Analysis\, Logic\, and Physics Sem
inar)\n\n\nAbstract\nLiquid crystals are an intermediate state of matter w
hich flow like liquids but retain molecular ordering similar to that of cr
ystals. Their physical properties make them ideal for a wide range of tech
nological applications. The molecules in smectic liquid crystals form well
-defined layers which slide across one another\; in fact\, this is what gi
ves soap its slippery feel. In this talk we will introduce a mathematical
model for smectics based on the minimization of a suitable energy and pres
ent recent results obtained jointly with Xiaodong Yan. No prior knowledge
of liquid crystals or the relevant mathematics will be assumed.\n

DESCRIPTION:Title: Higher indescribability and derived topologies\nby Brent Cody
(Virginia Commonwealth University) as part of VCU ALPS (Analysis\, Logic\,
and Physics Seminar)\n\n\nAbstract\nThe derived set of a subset of a topo
logical space\, also called the Cantor derivative of the set\, is the set
of limit points of the set. The concept was introduced by Cantor in 1872 a
nd set theory was initially developed in part to study derived sets on the
real line. Bagaria (2019) introduced the sequence of derived topologies o
n an ordinal $\\delta$\, which are topologies obtained from the interval t
opology on $\\delta$ by declaring certain derived sets to be open. Bagaria
used the large cardinal hypothesis of indescribability to show that in so
me models of set theory the first $\\delta$-many derived topologies on $\\
delta$ can be non-discrete and furthermore the non-isolated points of thes
e spaces can be characterized in terms of reflection properties. We will d
iscuss some natural generalizations of Bagaria’s results. For example\,
in order to move beyond the first $\\delta$-many derived topologies on $\\
delta$\, we introduce diagonal Cantor derivatives and indescribability pro
perties that involve certain kinds of infinitely long sentences.\n

DESCRIPTION:Title: The Riemann Hypothesis: History and Recent Work\nby Ken Ono (U

distribution of prime numbers\, stating that the nontrivial zeros of the
Riemann zeta function have a “real part” of one-half. A proof of the h
ypothesis would be world news and fetch a $1 million Millennium Prize. In
this lecture\, Ken Ono will discuss the mathematical meaning of the Rieman
n hypothesis and why it matters. Along the way\, he will tell tales of mys

minimizers in the infinite Wasserstein distance. As a consequence\, we ob
tain the uniqueness of local minimizers in this topology for a class of in
teraction potentials. We introduce a novel notion of concavity of the inte

local minimizers. We provide a family of interaction potentials such that
the support of the associated local minimizers has no isolated points and
any superlevel set has no interior points.\n

DESCRIPTION:Title: Stability for Faber-Krahn inequalities and the ACF formula\nby
Dennis Kriventsov (Rutgers University) as part of VCU ALPS (Analysis\, Lo

s that the first Dirichlet eigenvalue of the Laplacian on a domain is grea
ter than or equal to that of a ball of the same volume (and if equality ho
lds\, then the domain is a translate of a ball). Similar inequalities are
available on other manifolds where balls minimize perimeter over sets of a
given volume. I will present a new sharp stability theorem for such inequ
alities: if the eigenvalue of a set is close to a ball\, then the first ei
genfunction of that set must be close to the first eigenfunction of a ball
\, with the closeness quantified in an optimal way. I will also explain an
application of this to the behavior of the Alt-Caffarelli-Friedman monoto
nicity formula\, which has implications for free boundary problems with mu
ltiple phases. This is based on recent joint work with Mark Allen and Robi

DESCRIPTION:Title: When is a set of reals "weird"?\nby Corey Switzer (University
of Vienna) as part of VCU ALPS (Analysis\, Logic\, and Physics Seminar)\n
\n\nAbstract\nThe axiom of choice guarantees the existence of "weird" or\n
"pathological" sets of real numbers and their relatives. Examples\ninclude
well orderings of the reals\, Lebesgue non-measurable sets and\nnon-princ
iple ultrafilters (which can be coded as a set of reals). The\nguiding fra
mework here is that such sets cannot be "defined" in the\nsense that they
have no explicit definition\, which is why they do not\ncome up so often i
n analysis and related fields. In this talk I will try\nto explain what th
is means more precisely as well as show that\, in some\nmodels of set theo
ry\, "weird" sets actually have rather nice\ndefinitions. Time permitting\
, I will sketch some recent joint work with\nJeffrey Bergfalk and Vera Fis
cher showing that consistently many\npathological sets of reals can have v

me of its generalizations and results from the literature on the topic. Th
en I will consider the case where the repulsive potential is given by a ge

is integrable and its first moment is finite. This problem rewrites as an
isoperimetric problem where the classical perimeter is replaced by $P-\\g
amma P_\\varepsilon$\, where $\\gamma$ is a positive constant and $P_\\var
epsilon$ is a nonlocal functional converging to the perimeter as $\\vareps

DESCRIPTION:Title: Undecidability of Salce's Problem for abelian groups\nby Sean

n\nAbstract\nA cotorsion pair is a pair of classes $(\\mathcal{A}\,\\mathc
al{B})$ of abelian groups that is maximally orthogonal with respect to the
EXT functor. This concept was introduced in an influential paper of Salc
e in the 1970s\, where he asked whether every cotorsion pair is complete (
the cotorsion pair $(\\mathcal{A}\,\\mathcal{B})$ is complete if every abe
lian group is of the form $A/B$ for some $B \\in \\mathcal{B}$ and $A \\in
\\mathcal{A}$\; for example\, the cotorsion pair (Free abelian groups\, a
ll abelian groups) is complete). I will discuss my recent proof that Salc

DESCRIPTION:Title: Thin films of diblock copolymers\nby Riccardo Cristoferi (Rad

ls that have been used in many industrial applications ranging from uphols
tery foam to box tape\, from asphalt additives to drug delivery\, from pho
tonic crystals to nanoporous materials. The peculiar properties of block c
opolymers is their self-assembly property\, that leads to the creation of
fascinating patterns exhibiting interesting periodicity properties. The pa
ttern determines the physical properties of the compound\, and it is there
fore of great interest to being able to understand the mechanism behind th
is pattern formation. It has been seen in experiments that when block copo
lymers are constrained in thin films\, interfacial forces are dominant wit
h respect to bulk forces\, and therefore the landscape of patterns can be
very different from that of block copolymers in bulk.\n\nIn this talk we c
onsider a model\, inspired by one derived by Choksi and Ren\, to understan
d pattern formation of diblock copolymers in thin films. We will discuss t
he relaxed energy and partial regularity of mass constrained minimizers in
two spatial dimensions.\n\nThis talk is based on a joint work with Marco

DESCRIPTION:Title: A quantization of coarse structures and uniform Roe algebras\
nby David Sherman (University of Virginia) as part of VCU ALPS (Analysis\,
Logic\, and Physics Seminar)\n\n\nAbstract\nA coarse structure is a way o
f talking about "large-scale" properties. It is encoded in a family of re
lations that often\, but not always\, come from a metric. A coarse struct
ure naturally gives rise to Hilbert space operators that in turn generate
a so-called uniform Roe algebra.\n\nIn ongoing work with Bruno Braga and J
oe Eisner\, we use ideas of Weaver to construct "quantum" coarse structure
s and uniform Roe algebras in which the underlying set is replaced with an
arbitrary represented von Neumann algebra. The general theory immediatel
y applies to quantum metrics (suitably defined)\, but it is much richer.
We explain another source of examples based on measure instead of metric\,
leading to a large and easy-to-understand class of new C*-algebras.\n\nI
will present the big picture: where uniform Roe algebras come from\, how W
eaver's framework facilitates our definitions. I will focus on a few illu
strative examples and will not assume any familiarity with coarse structur
es or von Neumann algebras.\n

eminar)\n\nLecture held in Harris Hall 4145.\n\nAbstract\nThis talk is an
update on my ongoing project on the foundations of analysis. I will explai
n how extensions of maps between posets can be used as a unifying principl
e to conceptually understand basic notions such as limits\, continuity\, i
ntegrals\, derivatives\, and Dedekind cuts. If time permits\, I will show
how this approach leads to new proofs of familiar theorems.\n
