DG-MP-PDE Seminar: Closed geodesics and Alexandrov spaces
- Date: 04/15/2010
Lecturer(s):
Longzhi Lin (Johns Hopkins University)
Location:
University of British Columbia
Description:
In this talk we will present our recent work on ‘’Closed geodesics in Alexandrov spaces of curvature bounded from above’’. This is an extension of Colding and Minicozzi’s width-sweepout construction of closed geodesics on closed Riemannian manifold to the Alexandrov setting, which provides a generalized version of the Birkhoff-Lyusternik theorem on the existence of non-trivial closed geodesics. We will explain how the width-sweepout construction works and discuss some future work in this direction.
