Abstract

AbstractSuppose that G is a finitely generated group and WP⁡(G){\operatorname{WP}(G)}is the formal language of words defining the identity in G.We prove that if G is a virtually nilpotent group that is not virtually abelian, the fundamental group of a finite volume hyperbolic three-manifold, or a right-angled Artin group whose graph lies in a certain infinite class, then WP⁡(G){\operatorname{WP}(G)}is not a multiple context-free language.
