Fixed point indices of planar continuous maps

Luis Hernandez-Corbato, Francisco R. Ruiz del Portal

We characterize the sequences of fixed point indices {i(fn,p)}n≥1​ of fixed points that are isolated as an invariant set and continuous maps in the plane. In particular,…

Indices of the iterates of R3-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…
