Indices of the iterates of -homeomorphisms at Lyapunov stable fixed points
Francisco R. Ruiz del Portal, José Manuel Salazar
Given any positive sequence (\{c_n\}_{n \in {\Bbb N}}), we construct orientation preserving homeomorphisms (f:{\Bbb R}^3 \to {\Bbb R}^3) such that (Fix(f)=Per(f)=\{0\}), (0) is Lya…

J. Dydak, F. R. Ruiz del Portal
A morphism of a category which is simultaneously an epimorphism and a monomorphism is called a bimorphism. In \cite{DR2} we gave characterizations of monomorphisms (resp. epimorphi…
