Computing word length in alternate presentations of Thompsons group F


الملخص بالإنكليزية

We introduce a new method for computing the word length of an element of Thompsons group F with respect to a consecutive generating set of the form X_n={x_0,x_1,...,x_n}, which is a subset of the standard infinite generating set for F. We use this method to show that (F,X_n) is not almost convex, and has pockets of increasing, though bounded, depth dependent on n.
