The limit shape of convex hull peeling

Speaker: Charles Smart, Yale University

Location: Warren Weaver Hall 1302

Date: Tuesday, April 21, 2026, 11 a.m.

Synopsis:

If we peel a sufficiently dense and random point cloud by iteratively removing the points on its convex hull, then the resulting flow looks like motion by a power of Gaussian curvature.  I will discuss an older result along these lined by myself and Jeff Calder and a new result by my student Nhung Pham.
