Geometry and Topology Seminar: Estimating the reach of a submanifold

Presented by John Harvey, Swansea University
15 October 2020 13:05 in Zoom.

The reach is an important geometric invariant of submanifolds of Euclidean space. It is a real-valued global invariant incorporating information about the second fundamental form of the embedding and the location of the first critical point of the distance from the submanifold. In the subject of geometric inference, the reach plays a crucial role. I will give a new method of estimating the reach of a submanifold, developed jointly with Clément Berenfeld, Marc Hoffmann and Krishnan Shankar.

This will be an online talk. A Zoom invitation will be sent on Wednesday before the seminar.
