On Some Characterizations for Uniform Dichotomy of Evolution Operators in Banach Spaces
Mathematics, 2022 The present paper deals with two of the most significant behaviors in the theory of dynamical systems: the uniform exponential dichotomy and the uniform polynomial dichotomy for evolution operators in Banach spaces.

On some growth concepts for dichotomic behaviors of evolution operators
Annals of the West University of Timisoara: Mathematics and Computer Science, 2022 The aim of the present paper is to emphasize some growth concepts for the dichotomic behavior of evolution operators in Banach spaces. In fact, we approach the exponential growth, the polynomial growth and the h-growthfor both uniform and nonuniform ...

EKO: evolution kernel operators
European Physical Journal C: Particles and Fields, 2022 We present a new QCD evolution library for unpolarized parton distribution functions: EKO. The program solves DGLAP equations up to next-to-next-to-leading order.

Evolution Problems with m-Accretive Operators and Perturbations
Mathematics, 2022 This paper is devoted to the study of perturbation evolution problems involving time-dependent m-accretive operators. We present for a specific class of m-accretive operators with convex weakly compact-valued perturbation, some results about the ...

Approximating Common Fixed Points of an Evolution Family on a Metric Space via Mann Iteration
Journal of Mathematics, 2021 In this article, we present the set of all common fixed points of a subfamily of an evolution family in terms of intersection of all common fixed points of only two operators from the family; that is, for subset M of L, we have FM=FYϱ1,0∩FYϱ2,0, where ϱ1

On (h; k)-Dichotomy and (h; k)-Trichotomy of Noninvertible Evolution Operators in Banach Spaces
Annals of the West University of Timisoara: Mathematics and Computer Science, 2014 The paper considers some concepts of (h, k)-dichotomy and (h, k)-trichotomy for noninvertible evolution operators in Ba- nach spaces. A characterization of the (h, k)-trichotomy of an evolution operator in terms of (h, k)-dichotomy for two associated ...

(h, k)-Dichotomy and Lyapunov Type Norms
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 The paper considers a general concept of nonuniform (h, k)-dichotomy for evolution operators in Banach spaces. Two characterizations of this concept in terms of some families of norms compatible with the dichotomy projectors are given.
