Structural stability of attractor-repellor endomorphisms with singularities

چکیده
We prove a theorem on structural stability of smooth attractor-repellor endomorphisms of compact manifolds, with singularities. By attractor-repellor, we mean that the non-wandering set of the dynamics f is the disjoint union of a repulsive compact subset with a hyperbolic attractor on which f acts bijectively. The statement of this result is both infinitesimal and dynamical. Up to our knowledge, this is the first in this hybrid direction. Our results generalize also a Mather’s theorem in singularity theory which states that infinitesimal stability implies structural stability for composed mappings, to the larger category of laminations.

q-deformed statistical-mechanical property in the dynamics of trajectories en route to the Feigenbaum attractor.
We demonstrate that the dynamics toward and within the Feigenbaum attractor combine to form a q -deformed statistical-mechanical construction. The rate at which ensemble trajectories converge to the attractor (and to the repellor) is described by a q entropy obtained from a partition function generated by summing distances between neighboring positions of the attractor. The values of the q indi...
متن کاملStability Modulus Singular Sets
A new concept of stability, closely related to that of structural stability, is introduced and applied to the study of Cr endomorphisms with singularities. A map that is stable in this sense will be conjugated to each perturbation that is equivalent to it in a geometric sense. It will be shown that this kind of stability implies Axiom A, Omega-stability and that every critical point is wanderin...
متن کاملHomotopical Dynamics: Suspension and Duality
Flow type suspension and homotopy suspension agree for attractor-repellor homotopy data. The connection maps associated in Conley index theory to an attractor-repellor decomposition with respect to the direct flow and its inverse are SpanierWhitehead duals in the stably parallelizable context and are duals modulo a certain Thom construction in general.
متن کاملAttractor Networks on Complex Flag Manifolds
Robbin and Salamon showed in [10] that attractor-repellor networks and Lyapunov maps are equivalent concepts and illustrate this with the example of linear flows on projective spaces. In these examples the fixed points are linearly ordered with respect to the Smale order which makes the attractor-repellor network overly simple. In this paper we provide a class of examples in which the attractor...
متن کاملOn the Injectivity and Asymptotic Stability at Infinity
Let X : U → R be a differentiable vector field defined on the complement of a compact subset of the plane. Let Spc(X) denote the set of all eigenvalues of the differential DXz , when z varies in whole the domain U. We prove that the condition Spc(X) ⊂ {z ∈ C : R(z) < 0} is enough in order to obtain that the infinity to be either an attractor or a repellor for X. More precisely, we show that (i)...
