Abstract

Let F: Tn × I → Tn 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) of F in terms of its induced homomorphism. If L(F) is the one-parameter Lefschetz class of F then L(F) is given by L(F) = N(F)α, for some α∈ H11(Tn),ℤ).
