Let GG be a finitely generated group. We show that for any finite generating set AA, the language consisting of all geodesics in Cay(G,A)Cay(G,A) with a contracting property is a regular language. As an application, we show that any finitely generated group containing an infinite contracting geodesic must be either virtual…
