Peg Problems: *Cancelled*

SEMINARS, GAUGE-TOPOLOGY-SYMPLECTIC

Speaker:

Joshua Greene - Boston College

This event has been cancelled for today, April 29, 2022.

I will talk about joint work with Andrew Lobb related to Toeplitz's square peg problem, which asks whether every (continuous) Jordan curve in the Euclidean plane contains the vertices of a square. Specifically, we show that every smooth Jordan curve contains the vertices of a cyclic quadrilateral of any similarity class. I will describe the context for the result and its proof, which involves symplectic geometry in a surprising way.

This seminar was rescheduled from April 15, 2022**
