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.

Well-posed hemivariational inequalities

Numerical Functional Analysis and Optimization, 1995
This paper aims to present some basic results concerning the well-posedness in hemi-variational inequalities, that is a variational formulation introduced by P.D. Panagiotopoulos in order to describe the behavior of several complex structures in mechanics.

Static Hemivariational Inequalities

1993
In the present chapter we study static hemivariational inequalities concerning the existence of their solutions. Some approximation results are also given. We distinguish the coercive and the more difficult semicoercive case where the rigid body displacements play an important role.

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)
