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
functions using Möbius bands and elementary 4-dimensional topology. This
is joint work with Peter Feller.
