The (Nested) Word Problem

Published 23 Oct 2013 in cs.FL and math.GR | (1310.6283v3)

Abstract: In this article we provide a new perspective on the word problem of a group by using languages of nested words. These were introduced by Alur and Madhusudan as a way to model programming languages such as HTML. We demonstrate how a class of nested word languages called visibly pushdown can be used to study the word problem of virtually free groups in a natural way.
