Almost periodic solutions of differential inclusions governed by subdifferentials

open access: yesElectronic Journal of Differential Equations, 2016
Sufficient conditions are given to ensure the existence and eventually the uniqueness of bounded and almost periodic solutions of evolution equations governed by subdifferential operators.

On generalized derivatives for C1,1 vector optimization problems

open access: yesJournal of Applied Mathematics, 2003
We introduce generalized definitions of Peano and Riemann directional derivatives in order to obtain second-order optimality conditions for vector optimization problems involving C1,1 data.

High regularity of the solution of a nonlinear parabolic boundary-value problem

open access: yesElectronic Journal of Differential Equations, 2002
The aim of this paper is to report some results concerning high regularity of the solution of a nonlinear parabolic problem with a linear parabolic differential equation in one spatial dimension and nonlinear boundary conditions.

Asymptotically periodic solutions for differential and difference inclusions in Hilbert spaces

open access: yesElectronic Journal of Differential Equations, 2013
Let $H$ be a real Hilbert space and let $A:D(A)subset Ho H$ be a (possibly set-valued) maximal monotone operator. We investigate the existence of asymptotically periodic solutions to the differential equation (inclusion) $u'(t) + Au(t)i f(t) + g(t)$, $t ...

Necessary Optimality Conditions for a Class of Impulsive and Switching Systems

open access: yesJournal of Applied Mathematics, 2012
An optimal control problem for a class of hybrid impulsive and switching systems is considered. By defining switching times as part of extended state, we get the necessary optimality conditions for this problem.

Relaxed submonotone mappings

open access: yesAbstract and Applied Analysis, 2003
The notions of relaxed submonotone and relaxed monotone mappings in Banach spaces are introduced and many of their properties are investigated. For example, the Clarke subdifferential of a locally Lipschitz function in a separable Banach space is relaxed
