Topological stability and shadowing of zero-dimensional dynamical systems

open access: yesDiscrete and Continuous Dynamical Systems, 2019
In this paper, we examine the notion of topological stability and its relation to the shadowing properties in zero-dimensional spaces. Several counter-examples on the topological stability and the shadowing properties are given.

Stability of dynamical quantum phase transitions in quenched topological insulators: From multiband to disordered systems [PDF]

open access: yesPhysical Review B, 2019
Dynamical quantum phase transitions (DQPTs) represent a counterpart in non-equilibrium quantum time evolution of thermal phase transitions at equilibrium, where real time becomes analogous to a control parameter such as temperature.

Experimental quantum simulation of non-Hermitian dynamical topological states using stochastic Schrödinger equation [PDF]

open access: yesnpj Quantum Information, 2022
Noise is ubiquitous in real quantum systems, leading to non-Hermitian quantum dynamics, and may affect the fundamental states of matter. Here we report in an experiment a quantum simulation of the two-dimensional non-Hermitian quantum anomalous Hall (QAH)

Noise-to-State Stability in Probability for Random Complex Dynamical Systems on Networks

open access: yesMathematics, 2022
This paper studies noise-to-state stability in probability (NSSP) for random complex dynamical systems on networks (RCDSN). On the basis of Kirchhoff’s matrix theorem in graph theory, an appropriate Lyapunov function which combines with every subsystem ...

Topological stability and shadowing of dynamical systems from measure theoretical viewpoint

open access: yesTopological Methods in Nonlinear Analysis, 2021
In this paper it is proved that a topologically stable invariant measure has no sinks or sources in its support; an expansive homeomorphism is topologically stable if it exhibits a topologically stable nonatomic Borel support measure and a continuous map

Topological stability criteria for networking dynamical systems with Hermitian Jacobian

open access: yesEuropean Journal of Applied Mathematics, 2016
The central theme of complex systems research is to understand the emergent macroscopic properties of a system from the interplay of its microscopic constituents. The emergence of macroscopic properties is often intimately related to the structure of the microscopic interactions. Here, we present an analytical approach for deriving necessary conditions

Topological conjugacy and structural stability for discrete dynamical systems [PDF]

open access: yesBulletin of the American Mathematical Society, 1972
Topological conjugacy and various concepts of structural stability are defined, motivated, and criticized. Two basic problems emerge: characterization of structural stability and classification up to topological conjugacy. Solutions to these problems are

Fixed-point topology meets fractal memory: a Kutumba-stabilized framework for nonlocal fractal–fractional dynamics [PDF]

open access: yesScientific Reports
This paper presents an innovative synthesis of generalised fixed-point theory, advanced topological degree methodologies, and high-order computational frameworks for memory-driven dynamical systems. We expand contraction principles in complete metric and

Topological dynamics of control systems: Stability and attraction

open access: yesNonlinear Analysis: Theory, Methods & Applications, 1986
The authors study topological properties of control systems considered as dynamical polysystems. In this context they introduce such notions as stability, attraction, limit set and various prolongational sets. They derive some basic properties of these sets related to the stability question.

Level sets lemmas and unicity of critical point of invariants, tools for local stability and topological properties of dynamical systems

open access: yesSARAJEVO JOURNAL OF MATHEMATICS, 2012
We prove that the level curves of some differentiable functions of two variables with unique critical point are diffeomorphic to the circle T, and show how this result can be used in the study of local stability of dynamical systems in dimension 2 with ...
