Recent progress of mean curvature flow in higher codimension
Mean curvature flow is the gradient flow of the volume functional
of submanifolds smoothly immersed in a higher dimensional manifold.
Along the flow, volume of the submanifold is decreasing. The flow
satisfies a parabolic system of nonlinear partial differential
equations. In this talk, we shall discuss some recent progress of
mean curvature flow of submanifolds of codimension at least two
(the non-hypersurface case). In particular, motivated by geometric
and topological applications, we shall discuss the motion of
real 2-dimensional symplectic surfaces in a Kahler-Einstein surface
(complex 2-dimensional) and Lagrangian submanifolds in a Calabi-Yau
manifold.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
