On Ecker's local integral quantity at infinity for ancient mean curvature flows

Differential Geometry 2020-06-19 v2

Abstract

We point out that Ecker's local integral quantity agrees with Huisken's global integral quantity at infinity for ancient mean curvature flows if Huisken's one is finite on each time-slice. In particular, this means that the finiteness of Ecker's integral quantity at infinity implies the finiteness of the entropy at infinity.
