Daniel Ketover - Sharp entropy bounds of closed surfaces and min-max theory
Description : In 2012, Colding-Ilmanen-Minicozzi-White conjectured that the entropy of any closed surface in R^3 is at least that of the self-shrinking two-sphere. I will explain joint work with X. Zhou where we interpret this conjecture as a parabolic version of the Willmore problem and give a min-max proof ...

Feng Luo - Discrete conformal geometry of polyhedral surfaces and its convergence
Description : Our recent joint work with D. Gu established a discrete version of the uniformization theorem for compact polyhedral surfaces.   In this talk, we prove that discrete uniformizaton maps converge to conformal maps when the triangulations are sufficiently fine chosen.  We will also discuss the rela ...

Feng Luo - An introduction to discrete conformal geometry of polyhedral surfaces (Part 1)
Description : The goal of the course is to introduce some of the recent developments on discrete conformal geometry of polyhedral surfaces. We plan to cover the following topics. - The Andreev-Koebe-Thurston theorem on circle packing polyhedral metrics and Marden-Rodin’s proof - Thurston’s conjecture on the ...

Sylvain Maillot - An introduction to open 3-manifolds (Part 2)
Description : W. Thurston's geometrization program has lead to manyoutstanding results in 3-manifold theory. Thanks to worksof G. Perelman, J. Kahn and V. Markovic, D. Wise, and I. Agol among others, compact 3-manifolds can now beconsidered to be reasonably well-understood.By contrast, noncompact 3-manifolds ...
