Geometric Analysis Seminar

Closed hypersurfaces of low entropy in four-dimensional Euclidean space are isotopically trivial

Lu Wang (Caltech University)

Location:  zoom
Date & time: Tuesday, 27 April 2021 at 2:50PM - 3:50PM

Abstract: I will show that any closed connected hypersurface in four-dimensional Euclidean space with entropy less than or equal to that of the round cylinder is smoothly isotopic to the standard three-sphere. This is joint work with Jacob Bernstein.
