A Poincaré Formula for the Fixed Point Indices of the Iterates of Arbitrary Planar Homeomorphisms

Autor: José M. Salazar, Francisco R. Ruiz del Portal

Publikováno v: Fixed Point Theory and Applications, Vol 2010 (2010)

Let U⊂ℝ2 be an open subset and f:U→ℝ2 be an arbitrary local homeomorphism with Fix(f)={p}. We compute the fixed point indices of the iterates of f at p,iℝ2(fk,p), and we identify these indices in dynamical terms. Therefore, we obtain a sort

Isolating blocks of isolated invariant continua and fixed point index

Autor: José M. Salazar, Francisco R. Ruiz del Portal

Publikováno v: Journal of Fixed Point Theory and Applications. 21

In this paper we study some properties of isolated invariant continua for arbitrary homeomorphisms of $${{\mathbb {R}}}^n$$ . We study the existence of special isolating blocks for them which allow us to compute the fixed point indices of the iterate

Indices of the iterates of R3-homeomorphisms at Lyapunov stable fixed points

Autor: Francisco R. Ruiz del Portal, José M. Salazar

Publikováno v: Journal of Differential Equations. 244:1141-1156

Given any positive sequence { c n } n ∈ N , we construct orientation preserving homeomorphisms f : R 3 → R 3 such that Fix ( f ) = Per ( f ) = { 0 } , 0 is Lyapunov stable and lim sup | i ( f m , 0 ) | c m = ∞ . We will use our results to discu

Index 1 fixed points of orientation reversing planar homeomorphisms

Autor: José M. Salazar, Francisco R. Ruiz del Portal

Publikováno v: Topol. Methods Nonlinear Anal. 46, no. 1 (2015), 223-246

Let $U \subset {\mathbb R}^2$ be an open subset, $f\colon U \rightarrow f(U) \subset {\mathbb R}^2$ be an orientation reversing homeomorphism and let $0 \in U$ be an isolated, as a~periodic orbit, fixed point. The main theorem of this paper say

We use a notion (introduced in Topology 41 (2002), 1119–1212), which is stronger than the concept of filtration pair, to prove a stable/unstable manifold general theorem for local homeomorphisms of the plane in a neighborhood of an isolated fixed.

Fixed point index in symmetric products

Autor: José M. Salazar

Publikováno v: Transactions of the American Mathematical Society. 357:3493-3508

Let U be an open subset of a locally compact metric ANR X and let f: U → X he a continuous map. In this paper we study the fixed point index of the map that f induces in the n-symmetric product of X, F n (X). This index can detect the existence of

Shape index in metric spaces

Autor: Francisco R. Ruiz del Portal, José M. Salazar

Publikováno v: Fundamenta Mathematicae. 176:47-62

We extend the shape index, introduced by Robbin and Salamon and Mrozek, to locally defined maps in metric spaces. We show that this index is additive. Thus our construction answers in the affirmative two questions posed by Mrozek in [12]. We also pro
