Geometry and Topology Seminar: Characterizing non-positive curvature via an isoperimetric inequality.

Presented by Stefan Wenger., Fribourg.

4 February 2016 13:00 in CM221.

The aim of this talk is to show that a locally compact geodesic metric
space has non-positive curvature in the sense of Alexandrov (i.e. is a
closed curve of length $l$ bounds a disc of area at most $(4\pi)^{-1} l^2$.
