The Nielsen Coincidence Number of Maps into Tori.
, 2004 We give a formula for the Nielsen coincidence number of a pair of maps from a surface into the 2-torus. We also show that a similar formula gives the lower bound of the number of connected components of the coincidence set of a pair of maps between

Homotopies and the universal fixed point property
, 2013 A topological space has the fixed point property if every continuous self-map of that space has at least one fixed point. We demonstrate that there are serious restraints imposed by the requirement that there be a choice of fixed points that is ...

Rétractes Absolus de Voisinage Algébriques
, 2005 2000 Mathematics Subject Classification: 54C55, 54H25, 55M20.We introduce the class of algebraic ANRs. It is defined by replacing continuous maps by chain mappings in Lefschetz’s characterization of ANRs.

Model solvmanifolds for lefschetz and nielsen theories
, 2004 In this paper we construct a class of solvmanifolds and certain (diagonal type) self maps on them. These solvmanifolds and their maps serve firstly as rich source of examples. Secondly they serve as models for Nielsen theory in the sense that any map f :
