A quantitative version of Tao's result on the Toeplitz Square Peg Problem
arXiv:2106.01914
Abstract
Building on a result by Tao, we show that a certain type of simple closed curve in the plane given by the union of the graphs of two -Lipschitz functions inscribes a square whose sidelength is bounded from below by a universal constant times the maximum of the difference of the two functions.
