Speaker: Liu Yuning, Assistant Professor from NYU Shanghai Time: 9:30, March 30th, 2024Place: Room 332, No. 3 BuildingSponsor: SHNU College of Mathematics and Mechanical EngineeringIntroduction: We shall discuss the co-dimensional one interface limit and geometric motions of parabolic Ginzburg--Landau systems with potentials of high-dimensional wells. In particular combining modulated energy methods and weak convergence methods, we derive a sharp interface limit and the limiting harmonic heat fl

In this talk, we introduce a Heintze-Karcher-type inequality for hypersurfaces with boundary in convex domains. As a
