DESCRIPTION:Title: Symplectic fillings of lens spaces\nby Austin Christian (Georgia I
nstitute of Technology) as part of Early Career Math Colloquium\n\n\nAbstr
act\nIn physics\, the holographic principle suggests that some manifolds a
re completely determined by their boundaries --- that the manifold is some
how a projection of information which is encoded on the boundary. We will
explore this idea in the particular case of symplectic manifolds with con
tact boundaries\, asking for a count of the exact symplectic fillings of a
given contact manifold. Much of our time will be spent pretending to def
ine these words\, and eventually stating a precise question. Time permitt
ing\, we will discuss the answer to our question\, which is given by joint
work with Li\, and was independently obtained by Etnyre-Roy. We will do
our best to minimize technical prerequisites.\n

DESCRIPTION:Title: Long time behavior of the Nernst-Planck-Navier-Stokes system on a boun
ded domain\nby Fizay-Noah Lee (Princeton University) as part of Early
Career Math Colloquium\n\n\nAbstract\nThe Nernst-Planck-Navier-Stokes (NPN
S) system models electrodiffusion of ions in a fluid. After a brief overvi
ew of the state of the art of the relevant global regularity theory\, we d
iscuss the long time behavior of solutions. In the case of equilibrium bou
ndary conditions\, solutions converge to unique steady states\, which appr
oximately satisfy pointwise electroneutrality in the interior\, away from
the boundaries. In the case of nonequilibrium boundary conditions\, charac
terized by general Dirichlet boundary conditions for the ionic concentrati
ons\, we show that electroneutrality continues to hold in a space-time ave
raged sense\, for large times. Time permitting\, we also discuss the exist
ence of a finite dimensional global attractor for the solution map to the
NPNS system. The topics discussed include joint work with Peter Constantin
and Mihaela Ignatova.\n

olloquium\n\n\nAbstract\nWe will discuss recent results on gradient estima
tes for solutions to singular quasilinear elliptic (or parabolic) equation
s with measure data\, whose prototype is given by the elliptic (or parabol
ic) $p$-Laplace equation $-\\Delta_p u=\\mu$ (or $u_t-\\Delta_p u=\\mu$) w
ith $p\\in(1\,2)$. For these singular nonlinear equations\, we obtain poin
twise gradient estimates via linear elliptic (or parabolic) Riesz potentia
l and gradient continuity results via certain assumptions on the linear Ri
esz potential. This is based on joint works with Hongjie Dong.\n

DESCRIPTION:Title: Efficient Numerical Methods For The Monge-Ampère Equation\nby Jak
e Brusca (New Jersey Institute of Technology) as part of Early Career Math
Colloquium\n\n\nAbstract\nThe Monge-Ampère equation is a fully nonlinear
degenerate elliptic PDE used in a large number of applications including
mesh generation\, optical design\, and medical image processing. The devel
opment of convergent numerical methods for this PDE has been guided by the
Barles and Souganidis framework\, which guarantees a monotone scheme will
converge to the unique weak (viscosity) solution provided the PDE satisfi
es a comparison principle. However\, monotone scemes rely on wide stencils
\, which traditionally suffer from high computational costs and low accura
cy due. We will address these challenges by 1) introducing an improved mon
otone discretization using an integral representation of the Monge-Ampère
operator and 2) developing highly parallelizable nonlinear root finders f
or monotone schemes. This presentation is based on joint work with Tadanag
a Takahashi\, Yassine Boubendir\, and Brittany Hamfeldt.\n

DESCRIPTION:Title: Nonlinear stability and long time behavior for the 2D incompressible M
HD system with partial dissipation\nby Wen Feng (Niagara University) a
s part of Early Career Math Colloquium\n\n\nAbstract\nIn this talk\, we wi
ll discuss the decay results on a 2D magnetohydrodynamic (MHD) system with
only vertical dissipation or horizontal dissipation. For vertical dissipa
tion\, we show that the H^2-norm of any perturbation near a background mag
netic field actually decays algebraically in time. Mathematically this res
ult along with its proof offers a new and effective approach to the large-
time behavior on partially dissipated systems. For horizontal dissipation\
, we show the stability result on the perturbations near a background magn
etic field. In addition\, the solution converges to its horizontal average
asymptotically.\n

DESCRIPTION:Title: Two topics in self-similar singularity formation\nby Federico Pasq
ualotto (Duke University) as part of Early Career Math Colloquium\n\n\nAbs
tract\nSelf-similarity is a powerful tool to investigate the "universal" b
ehavior of certain nonlinear PDEs in which coherent structures (such as si
ngularities) appear. In this talk\, I will describe two results in which s
elf-similarity plays a crucial role.\n\nThe first result\, joint with Sung
-Jin Oh\, concerns singularity formation for a wide class of one-dimension
al models. We construct approximately self-similar "shock forming" solutio
ns to a class of dispersive and dissipative perturbations of the classical
Burgers equation. This class includes the Whitham equation arising in wat
er waves and the fractional KdV equation with dispersive term of order $\\
alpha \\in [0\,1)$. Our result appears to be the first construction of gra
dient blow-up for fractional KdV in the range $\\alpha \\in [2/3\,1)$.\n\n
In the second result\, joint with Tarek Elgindi\, we focus on the axisymme
tric 3D Euler equations in the whole space $\\mathbb{R}^3$ (and its 2D app
roximate model\, the Boussinesq system) . We provide a novel mechanism for
self-similar singularity formation starting from $C^{1\,\\alpha}$ initial
data with non-trivial swirl. Unlike previous constructions\, the blow-up
happens away from the symmetry axis.\n\nhttps://arizona.zoom.us/j/82763762

DESCRIPTION:Title: A variational approach to the existence problem for a degenerate cross
-diffusion model\nby Havva Yoldaş (TU Delft) as part of Early Career
Math Colloquium\n\n\nAbstract\nIn this talk\, we look at a cross-diffusion
system consisting of two Fokker-Planck equations where the gradient of th
e density for each species acts as a potential for the other one. The syst
em is the gradient flow for the Wasserstein distance of a functional which
is not lower semi-continuous\, thus it is not well-posed. We then compute
the convexification of the integral and provide an existence proof in a s
uitable sense for the gradient flow of the corresponding relaxed functiona
l. The talk is based on a joint work with R. Ducasse and F. Santambrogio (
Calc Var PDE\, 2022).\n

DESCRIPTION:Title: Global Solutions to Nonconvex Problems by Evolution of Hamilton-Jacobi
PDEs\nby Samy Wu Fung (Colorado School of Mines) as part of Early Car
eer Math Colloquium\n\n\nAbstract\nComputing tasks may often be posed as o
ptimization problems. The objective functions for real-world scenarios are
often nonconvex and/or nondifferentiable. State-of-the-art methods for so
lving these problems typically only guarantee convergence to local minima.
This work presents Hamilton-Jacobi-based Moreau Adaptive Descent (HJ-MAD)
\, a zero-order algorithm with guaranteed convergence to global minima\, a
ssuming continuity of the objective function. The core idea is to compute
gradients of the Moreau envelope of the objective (which is “piece-wise
convex”) with adaptive smoothing parameters. Gradients of the Moreau env
elope are approximated by employing the Hopf-Lax formula for the viscous H
amilton Jacobi equation. Provided numerical examples illustrate global con
vergence.\n

DESCRIPTION:Title: Ensuring Exploration in Graph-Based Active Learning\nby Kevin Mil
ler (Oden Institute at UT Austin) as part of Early Career Math Colloquium\
n\n\nAbstract\nUncertainty sampling has traditionally been the de facto\,
simplest acquisition function for active learning in semi-supervised learn
ing. Comparatively cheap to compute and straightforward to interpret\, unc
ertainty sampling has been known to suffer from myopic sampling bias that
fails to properly explore the extent of geometric structure of the dataset
prior to exploiting learning decision boundaries. As such\, most work in
active learning for graph-based learning has focused on the design of more
intricate acquisition functions that are explorative in nature\, though a
re almost always more costly to compute. We show that exploration and expl
oitation in graph-based semi-supervised learning can be achieved by ensuri
ng that the underlying graph-based model reflects uncertainty at unlabeled
nodes that in turn captures the underlying clustering structure of the da
taset. We present theoretical results and empirical evidence to demonstrat
e that Poisson reweighted Laplacian learning\, which has a well-defined co
ntinuum limit model\, allows us to ensure exploration by simply applying a
specific form of uncertainty sampling.\n

DESCRIPTION:Title: On the regularity of the axisymmetric\, swirl-free solutions of the E
uler equation in four and higher dimensions\nby Evan Miller (Universit
y of British Columbia and the PIMS) as part of Early Career Math Colloquiu
m\n\n\nAbstract\nIn this talk\, we will discuss the axisymmetric\, swirl-f
ree Euler\nequation in four and higher dimensions. We will show that in fo
ur and\nhigher dimensions the axisymmetric\, swirl-free Euler equation has
\nproperties which could allow finite-time singularity formation of a form
\nthat is excluded in three dimensions. We will also consider a model\nequ
ation that is obtained by taking the infinite-dimensional limit of the\nvo
rticity equation in this setup. This model exhibits finite-time blowup of\
na Burgers shock type. The blowup result for the infinite dimensional mode
l\nequation heavily suggests that smooth solutions of the Euler equation\n
exhibit finite-time blowup in sufficiently high dimensions.\n

DESCRIPTION:Title: Boundary stabilization of nonlinear dynamics of acoustics waves under
the JMGT equation\nby Marcelo Bongarti (Weierstrass Institute for Ap
plied Analysis and Stochastics) as part of Early Career Math Colloquium\n\
n\nAbstract\nThe Jordan–Morse–Gibbson–Thompson (JMGT) equation is a
third-order in time partial differential equation (PDE) model describing n
onlinear propagation of sound in an acoustic medium. Its study is motivate
d by a large array of applications arising in engineering and medical scie
nces\, especially high intensity focused ultrasound (HIFU) technologies. T
he important feature is that the model avoids the infinite speed of propag
ation paradox associated with the classical second order in time equation
known as Westervelt’s equation. The third order in time derivative is du
e to the shift from parabolic to the hyperbolic model\, the latter being a
singular perturbation (w.r.t the thermal time relaxation) of the former.
In this talk we will present several results pertinent to the model\, most
ly from the point of view of boundary stabilization. These include: (i) lo
cal and global wellposedness\, (ii) asymptotic analysis when the thermal r
elaxation parameter vanishes\, and (iii) boundary stabillizability of JMGT
in the critical and degenerate case.\n

2D Euler-type equations (specifically\, logEuler and hypodissipative Navie

DESCRIPTION:Title: Low regularity solutions for quasilinear PDEs\nby Albert Ai (Univ
ersity of Wisconsin-Madison) as part of Early Career Math Colloquium\n\n\n
Abstract\nIn this talk\, we will consider the low regularity well-posednes
s problem for a pair of quasilinear dispersive PDEs: the nonlinear wave eq
uation\, and the water waves equations. Two classical methods\, energy est
imates and Strichartz estimates\, have historically yielded substantial bu
t partial results toward advancing the low regularity theory. We will see
how\, using a special structure of the equations known as a normal form st
ructure\, combined with tools from harmonic and microlocal analysis\, we c
an refine these classical methods to improve the known results for low reg
ularity well-posedness.\n
