Ovidiu Munteanu (Univ. of Connecticut) ``Poisson equation on complete manifolds''
Abstract: I will discuss sharp estimates for the Green's function on
complete manifolds and their applications to solving the Poisson
equation. I will mention new sharp results about existence of
solutions and their asymptotic behavior. Some new results
about gradient Ricci solitons will be presented as application.

Jacob Bernstein (Johns Hopkins) ``Surfaces of Low Entropy''
Abstract: Following Colding and Minicozzi, we consider the entropy of
(hyper)-surfaces in Euclidean space. This is a numerical measure of
the geometric complexity of the surface. In addition, this quantity
is intimately tied to to the singularity formation of the mean
curvature flow which is a natural geometric heat flow of
submanifolds. In the talk, I will discuss several results that show
that closed surfaces for which the entropy is small are simple in
various senses. This is all joint work with L. Wang.
