Semicoercive variational hemivariational inequalities

Journal of Global Optimization, 1995
The authors have introduced a concept of recession function associated to the Clarke generalized directional derivative of a locally Lipschitz function. Using this concept, some new necessary and sufficient conditions for the existence of a general hemivariational inequality problem are given.

On a class of nonlinear variational–hemivariational inequalities

Applicable Analysis, 2004
A three critical points theorem for nondifferentiable functions is pointed out and an existence result of multiple solutions for a Neumann elliptic variational–hemivariational inequality involving the p-laplacian is established. As an application, a Neumann problem for elliptic equations with discontinuous nonlinearities is studied.

Semicoercive variational hemivariational inequalities

Applicable Analysis, 1997
The aim of this paper is the study of semicoercive variational hemivariational inequalities. For this study the critical point theory of Ambrosetti, Rabinowitz and Szulkin has been extended for nonsmooth functionals. Moreover, a Saddle Point Theorem and a symmetric version of the Mountain Pass Theorem have been used.

"A Fixed Point Approach of Variational-Hemivariational Inequalities"

Carpathian Journal of Mathematics, 2022
"In this paper we provide a new approach in the study of a variational-hemivariational inequal- ity in Hilbert space, based on the theory of maximal monotone operators and the Banach fixed point theorem. First, we introduce the inequality problem we are interested in, list the assumptions on the data and show that it is governed by a multivalued ...

Variational, Hemivariational and Variational-Hemivariational Inequalities: Existence Results

2003
The celebrated Hartman-Stampacchia theorem (see [6], Lemma 3.1, or [9], Theorem I.3.1) asserts that if V is a finite dimensional Banach space, K ⊂ V is non-empty, compact and convex, A : K → V* is continuous, then there exists u ∈ K such that, for every v ∈ K, $$\langle Au,v - u\rangle \geqslant 0.$$ (6.1)

Numerical analysis of stationary variational-hemivariational inequalities

Numerische Mathematik, 2018
The authors are concerned with FEM solutions to stationary variational-hemivariational inequalities. They pay attention to the existence and uniqueness results for such inequalities, as well as to the rigorous formulation for the FEM in order to accurately solve them.
