Positivity and contractivity in the dynamics of clusters’ splitting with derivative of fractional order

open access: yesOpen Mathematics, 2015
Classical models of clusters’ fission have failed to fully explain strange phenomenons like the phenomenon of shattering (Ziff et al., 1987) and the sudden appearance of infinitely many particles in some systems with initial finite particles number ...

Existence and Ulam stability of initial value problem for fractional perturbed functional q-difference equations

open access: yes
In this work, we discuss the existence and uniqueness of solutions to the initial value problem for perturbed functional fractional q-difference equations involving q-derivative of the Caputo sense. By applying Banach contraction principle and Burton and

Existence and Multiplicity Results for Systems of First-Order Differential Equations via the Method of Solution-Regions

open access: yesAdvanced Nonlinear Studies, 2018
In this paper, we establish existence and multiplicity results for systems of first-order differential equations. To this end, we introduce the method of solution-regions.

Notes on Knaster-Tarski Theorem versus Monotone Nonexpansive Mappings

open access: yesMoroccan Journal of Pure and Applied Analysis, 2018
The purpose of this note is to discuss the recent paper of Espínola and Wiśnicki about the fixed point theory of monotone nonexpansive mappings. In their work, it is claimed that most of the fixed point results of this class of mappings boil down to the ...

Existence of solutions for nonlinear problems involving mixed fractional derivatives with p(x)-Laplacian operator

open access: yesDemonstratio Mathematica
In this article, a functional boundary value problem involving mixed fractional derivatives with p(x)p\left(x)-Laplacian operator is investigated. Based on the fixed point theorems and Mawhin’s coincidence theory’s extension theory, some existence ...

Some remarks on the absolute continuity of set-valued mappings

open access: yes, 2017
В последнее время многие авторы рассматривали вопросы существования, единственности и свойства решений множественнозначных дифференциальных и интегро-дифференциальных уравнений, уравнений высших порядков, исследовали импульсные и управляемые системы в ...

Transformation of p-gradient flows to p′-gradient flows in metric spaces

open access: yesAnalysis and Geometry in Metric Spaces
We explicitly construct parameter transformations between gradient flows in metric spaces, called curves of maximal slope, having different exponents when the associated function and the associated metric space satisfy a suitable convexity condition ...
