A Fast Algorithm for Stallings' Folding Process

Group Theory 2014-03-27 v1

Abstract

We show that for a fixed free group F and an arbitrary finitely generated subgroup H (as given above) we can perform the Stalling's folding process in time O(N log^*(N)), where N is the sum of the word lengths of the given generators of H.
