Title: Boundary Value Problems for Dirac-harmonic Maps and Their Heat Flows

Abstract: In this talk, we shall discuss some boundary value problems for Dirac-harmonic maps and present some recent progresses on the heat flow approach to the existence problem.

Title: Finite Morse Index Solutions of the Allen-Cahn Equation


Abstract: In this talk I will report a recent proof of the conjecture that finite Morse index solutions of the Allen-Cahn equation in the plane have finitely many ends. I will discuss some ideas in this proof, including the curvature estimate of Schoen type, the uniform second order estimates of clustering interfaces and its connection with Toda systems. This is a joint work with Juncheng Wei.

Title: Some curvature flows in warped product manifolds


Abstract: In this talk, we will discuss some curvature flows in warped product manifolds.  They include curve shortening flows, mean curvature type flows and inverse mean curvature flows.  If the initial datum is a starshaped graph,  we will see how various conditions imply long time existence and certain asymptotic behaviors of these flows.  We also discuss the connection between our results and some other recent works.
