On some topological realizations of groups and homomorphisms

Pedro J. Chocano, Manuel A. Morón, Francisco R. Ruiz del Portal

Let be a homomorphism of groups, we construct a topological space such that its group of homeomorphisms is isomorphic to , its group of homotopy classes…

Coincidence theorems for finite topological spaces

Pedro J. Chocano, Manuel A. Morón, Francisco R. Ruiz del Portal

We adapt the definition of the Vietoris map to the framework of finite topological spaces and we prove some coincidence theorems. From them, we deduce a Lefschetz fixed point theor…
