Abstract

Let F:Tn×ITnF: T^{n} \times I \to T^{n} be a homotopy on a n-dimensional torus. The main purpose of this paper is to present a formula for the one-parameter Nielsen number N(F)N(F) of FF in terms of its induced homomorphism. If L(F)L(F) is the one-parameter Lefschetz class of FF then L(F)L(F) is given by L(F)= N(F)α,L(F) = \ N(F)\alpha, for some αH1(π1(Tn),Z).\alpha \in H_{1}(\pi_{1}(T^{n}),\mathbb{Z}).
