Abstract

We prove that Thompson's group F is not minimally almost convex with respect to any generating set which is a subset of the standard infinite generating set for F and which contains x 1. We use this to show that F is not almost convex with respect to any generating set which is a subset of the standard infinite generating set, generalizing results in Horak, Stein, and Taback, Int. J. Algebra Comput. 19: 963997, 2009.
