Smoothness of topological equivalence on the half line for nonautonomous systems
(Cambridge University Press, 2020)
We study the differentiability properties of the topological equivalence between a uniformly asymptotically stable linear nonautonomous system and a perturbed system with suitable nonlinearities. For this purpose, we ...
Dichotomy spectrum and almost topological conjugacy on nonautonomus unbounded difference systems
(American Institute of Mathematical Sciences, 2018)
© 2018 American Institute of Mathematical Sciences. All rights reserved. We construct a bijection between the solutions of a linear system of nonautonomous difference equations which is uniformly asymptotically stable and ...
Adapted hyperbolic polygons and symplectic representations for group actions on Riemann surfaces
(Elsevier, 2013-03)
We prove that given a finite group G together with a set of fixed geometric generators, there is a family of special hyperbolic polygons that uniformize the Riemann surfaces admitting the action of G with the given geometric ...
Nonuniform almost reducibility of nonautonomous linear differential equations
(Elsevier, 2020)
We prove that a linear nonautonomous differential system with nonuniform hyperbolicity on the half line can be written as diagonal system with a perturbation which is small enough. Moreover we show that the diagonal terms ...
Application of neural network and time-domain feature extraction techniques for determining volumetric percentages and the type of two phase flow regimes independent of scale layer thickness
