One-parameter Lefschetz class of homotopies on torus

The main result this paper states that if $F: T \times I \to T$ is a homotopy on torus then the one-parameter Lefschetz class $L(F)$ of $F$ is given by $L(F) = \pm N(F)α$, where $N(F)$ is the one-parameter Nielsen number of $F$ and $α$ is one of the two generators in $H_{1}(π_{1}(T),\mathbb{Z})$.

Minimal fixed point set of maps on Torus Fiber Bundles over the Circle

The main purpose this work is to study the minimal fixed point set of fiber-preserving maps for spaces which are fiber bundles over the circle and the fiber is the torus. Using the one-parameter fixed point theory is possible to describe these sets in terms of the fundamental group and the induced homomorphism.
