Abstract
In order to compute the Nielsen number N(f) of a self-map f : X → X, some Reidemeister classes in the fundamental group π1(X) need to be distinguished. In this paper some algebraic results are given which allow distinguishing Reidemeister classes and hence computing the Reidemeister number of some maps. Examples of computations are presented
