Existence Results for Nonconvex Nonautonomous Differential Inclusions in Hilbert Spaces

open access: yesMathematics
We establish a solvability criterion for nonautonomous time-evolution inclusions governed by the right-hand side without the convexity assumption. In this study, we examine the problem x˙(t)∈F(t,x(t))a.e.onI0:=[0,T0], for some T0>0, where F has a closed ...

On Fr\'{e}chet Subdifferential of Supremum for Arbitrary Family of Continuous Functions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
The paper focuses on the Fr\'{e}chet subdifferential of the pointwise supremum of the family of functions taken over arbitrary index sets. The all functions in the corresponding family are defined on a Fr\'{e}chet smooth space; this class of Banach ...

Optimality conditions via weak subdifferentials in reflexive Banach spaces

open access: yes, 2017
In this paper the relation between the weak subdifferentials and the directional derivatives, as well as optimality conditions for nonconvex optimization problems in reflexive Banach spaces, are investigated. It partly generalizes several related results

Automatic feedback control for one class of contact piezoelectric problems

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2014
In this paper we investigate the dynamics of solutions of the second order evolution inclusion with discontinuous interaction function which can be represented as the difference of subdifferentials.

Existence Results and Gap Functions for Nonsmooth Weak Vector Variational-Hemivariational Inequality Problems on Hadamard Manifolds

open access: yesMathematics
In this paper, we consider a class of nonsmooth weak vector variational-hemivariational inequality problems (abbreviated as, WVVHVIP) in the framework of Hadamard manifolds.

Calculus of second-order subdifferentials in infinite dimensions

open access: yes, 2002
We study two types of second-order subdifferentials of extended-real-valued functions on Banach spaces that are important for applications in variational analysis, especially to sensitivity issues and second-order optimality conditions.

Semistrictly and neatly quasiconvex programming using lower global subdifferentials

open access: yes, 2023
: The main goal of this paper is to investigate the properties and connections of neatly and semistrictly quasiconvex functions, especially when they appear in constrained and unconstrained optimization problems.
