Square pegs and non-orientable surfaces
Marco Golla
(Universite de Nantes)
Abstract
The square peg problem asks whether every Jordan curve in the
plane contains the vertices of a square. Inspired by Hugelmeyer's approach
for smooth curves, we give a topological proof for "locally 1-Lipschitz"
curves using 4-dimensional topology.
