Viability problem with perturbation in Hilbert space

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2007
This paper deals with the existence result of viable solutions of the differential inclusion $$\dot{x}(t) \in f(t,x(t)) + F(x(t))$$ $$x(t) \in K \quad \text{on } [0,T],$$ where $K$ is a locally compact subset in separable Hilbert space $H,$ $(f(s,\cdot))

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

Hidden maximal monotonicity in evolutionary variational-hemivariational inequalities

open access: yesNonlinear Analysis, 2021
In this paper, we propose a new methodology to study evolutionary variational-hemivariational inequalities based on the theory of evolution equations governed by maximal monotone operators. More precisely, the proposed approach, based on a hidden maximal

Minimization of nonsmooth integral functionals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
In this paper we examine optimization problems involving multidimensional nonsmooth integral functionals defined on Sobolev spaces. We obtain necessary and sufficient conditions for optimality in convex, finite dimensional problems using techniques from ...

Weak Solutions and Optimal Control of Hemivariational Evolutionary Navier-Stokes Equations under Rauch Condition

open access: yesJournal of Function Spaces, 2020
In this paper, we consider the evolutionary Navier-Stokes equations subject to the nonslip boundary condition together with a Clarke subdifferential relation between the dynamic pressure and the normal component of the velocity. Under the Rauch condition,

Separable determination of integrability and minimality of the Clarke subdifferential mapping [PDF]

open access: yesProceedings of the American Mathematical Society, 1999
In this paper we show that the study of integrability and D D -representability of Lipschitz functions defined on arbitrary

Operational Properties of SCN Function, Optimization Condition, and Exactness of Penalty Function for SCN Optimization

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This paper defines a strong convertible nonconvex (SCN) function for solving the unconstrained optimization problems with the nonconvex or nonsmooth (nondifferentiable) function. First, the concept of SCN function is defined, where the SCN functions are nonconvex or nonsmooth.

On the Clarke Subdifferential of an Integral Functional on Lp, 1 ≤ p < ∞

open access: yes, 1998
Given an integral functional defined on Lp, 1 ≤ p < ∞, under a growth condition we give an upper bound of the Clarke directional derivative and we obtain a nice inclusion between the Clarke subdifferential of the integral functional and the set of ...
