On Negative Escape Time in Semidynamical Systems
We present the correction of some incorrectness in the paper [12]. The paper [12] is of fundamental meaning in the theory of semidynamical systems. In this paper R.C. McCann defined the negative escape time in semidynamical systems which is, intuitively, “the minimum time length of all negative trajectories through x” . This concept is of great importance in many investigations in the theory. I...
متن کاملGlobal Attractors and Steady States for Uniformly Persistent Dynamical Systems
By appealing to the theory of global attractors on complete metric spaces, we obtain weaker sufficient conditions for the existence of interior global attractors for uniformly persistent dynamical systems, and hence generalize the earlier results on coexistence steady states. We also provide examples to show applicability of our interior fixed point theorem in the case of convex κ-contracting m...
متن کاملSemidynamical Systems and Hilbert’s Fifth Problem
g : [0,∞)×X → X and g(t, x) = T (t)x, t ≥ 0, x ∈ X, then g is continuous. For many semigroups strong continuity implies joint continuity. A function gx as in (1) is called a trajectory of T . If T has domain all of R instead of just [0,∞) we refer to T as a ‘group’. In his Fifth Problem, Hilbert asked whether assumptions of differentiability that Sophus Lie made were actually a consequence of L...
متن کاملThe Notion of Topological Entropy in Fuzzy Metric Spaces
The aim of this paper is to extend the notion of topological entropy for fuzzy semidynamical systems created by a self-map on a fuzzy metric space. We show that if a metric space has two uniformly equivalent metrics, then fuzzy entropy is a constant up to these two metrics. We present a method to construct chaotic fuzzy semidynamical systems with arbitrary large fuzzy entropy. We also prove tha...
متن کاملTopologic Conjugation and Asymptotic Stability in Impulsive Semidynamical Systems
We prove several results concerning topologic conjugation of two impulsive semidynamical systems. In particular, we prove that the homeomorphism which defines the topologic conjugation takes impulsive points to impulsive points; it also preserves properties as limit sets, prolongation limit sets, the minimality of positive impulsive orbits as well as stability and invariance with respect to the...
