A group G has the R∞-property if for every φ∈Aut(G), there are an infinite number of φ-twisted conjugacy classes of elements in G. In this note, we determine the R∞-property for G=π1(M) for all geomet..

A group G has the R∞-property if for every φ∈Aut(G), there are an infinite number of φ-twisted conjugacy classes of elements in G. In this note, we determine the R∞-property for G=π1(M) for all geometric 3-manifolds M.
