On a Class of Fully Nonlinear Flow in K\"ahler Geometry
2:00pm|S-101

We study a class of fully nonlinear metric flow on K\"ahler manifolds, which includes the J-flow as a special case. We provide a sufficient and necessary condition for the long time convergence of the flow, generalizing the result of Song-Weinkove...

The Regularized Determinant of a Four-Manifold
Matt Gursky
2:00pm|S-101

I will give an overview of a variational problem in conformal geometry/spectral theory. Beginning with a formula for the determinant of the laplacian for a surface and the work of Osgood-Phillips-Sarnak, I will explain some attempts to generalize...

Stability Problems for Crystals, I
Alessio Figalli
2:00pm|S-101

The equilibrium shape of a crystal is determined by the minimization under a volume constraint of its free energy, consisting of an anisotropic interfacial surface energy plus a bulk potential energy. In the absence of the potential term, the...

Infinite/Finite Time Blow-Up for Aggregation Equations in Mathematical Biology
Jose Carrillo
11:15am|S-101

In this talk I will review two recent works in collaboration with A. Bertozzi and T. Laurent and with M. DiFrancesco, A. Figalli, T. Laurent and D. Slepcev in which we prove infinite/finite time blow-up for generic initial data in several models...

Geometric PDE Seminar

Homogenization of Nonlinear Stochastic Evolution Problems in Non Periodically Perforated Domains
3:30pm|S-101

The talk is devoted to the homogenization of a stochastic evolution problem with non Lipschitz forcing. The problem is considered in a sequence of perforated cylindrical domains obtained from the removal of tiny cylinders from a fixed one (the...

Green Functions and Mean Field Equation at Critical Parameters on Torus
2:00pm|S-101

The location of blowup points is often related to critical points of Green function. In fact, Green function plays a important role to understand the solutions structure of mean field equations. We will show how to use the elliptic function and the...
