A Relaxed Version of the Cutting Method with Approximation of the Constraint Region

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
A cutting method was proposed for solving the convex programming problem. The method assumes that the constraint region of the problem is embedded into some polyhedral sets for constructing iteration points.

Weakened subdifferentials and Frechet differentiability of real functions [PDF]

open access: yes
Let X be a real Banach space and f : X ! R [ {+1}. It is well known that the Clarke subdifferential @ f(x) of the function f at x 2 int dom f is a singleton if and only if f is strongly differentiable (then @ f(x) = {Dsf(x)}, where Dsf(x) is the strong ...

Inexact Inertial Proximal Algorithm for Maximal Monotone Operators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, convergence of the sequence generated by the inexact form of the inertial proximal algorithm is studied. This algorithm which is obtained by the discretization of a nonlinear oscillator with damping dynamical system, has been introduced by

Homological differential calculus

open access: yes, 2019
This article provides a definition of a subdifferential for continuous functions based on homological considerations. We show that it satisfies all the requirement for a good notion of subdifferential.

On a time-dependent subdifferential evolution inclusion with a nonconvex upper-semicontinuous perturbation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2005
We investigate the existence of local approximate and strong solutions for a time-dependent subdifferential evolution inclusion with a nonconvex upper-semicontinuous perturbation.

Periodic solutions for time-dependent subdifferential evolution inclusions

open access: yes, 2017
We consider evolution inclusions driven by a time dependent subdifferential plus a multivalued perturbation. We look for periodic solutions. We prove existence results for the convex problem (convex valued perturbation), for the nonconvex problem ...

On the use of semi-closed sets and functions in convex analysis

open access: yesOpen Mathematics, 2015
The main aim of this short note is to show that the subdifferentiability and duality results established by Laghdir (2005), Laghdir and Benabbou (2007), and Alimohammady et al. (2011), stated in Fréchet spaces, are consequences of the corresponding known

A viability result for second-order differential inclusions

open access: yesElectronic Journal of Differential Equations, 2002
We prove a viability result for the second-order differential inclusion $$ x''in F(x,x'),quad (x(0), x'(0))=(x_0,y_0)in Q:=Kimes Omega, $$ where $K$ is a closed and $Omega$ is an open subsets of $mathbb{R}^m$, and is an upper semicontinuous set-valued ...

Existence of infinitely many periodic subharmonic solutions for nonlinear non-autonomous neutral differential equations

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we study the existence of an infinite number of subharmonic periodic solutions to a class of second-order neutral nonlinear functional differential equations.

Characterization of the Strong Metric Subregularity of the Mordukhovich Subdifferential on Asplund Spaces

open access: yesAbstract and Applied Analysis, 2014
We mainly present several equivalent characterizations of the strong metric subregularity of the Mordukhovich subdifferential for an extended-real-valued lower semicontinuous, prox-regular, and subdifferentially continuous function acting on an Asplund ...
