Noncoercive Perturbed Densely Defined Operators and Application to Parabolic Problems

open access: yesAbstract and Applied Analysis, Volume 2015, Issue 1, 2015., 2015
Let X be a real locally uniformly convex reflexive separable Banach space with locally uniformly convex dual space X∗. Let T:X⊇D(T)→2X∗ be maximal monotone and S : X⊇D(S) → X∗ quasibounded generalized pseudomonotone such that there exists a real reflexive separable Banach space W ⊂ D(S), dense and continuously embedded in X. Assume, further, that there

Superlinear elliptic hemivariational inequalities

open access: yesHacettepe Journal of Mathematics and Statistics, 2023
We study a nonlinear nonhomogeneous Dirichlet problem with a nonsmooth potential which is superlinear but without satisfying the Ambrosetti-Rabinowitz condition. Using the nonsmooth critical point theory and critical groups we prove two multiplicity theorems producing three and five solutions respectively. In the second multiplicity theorem, we provide

On a Class of Variational‐Hemivariational Inequalities Involving Upper Semicontinuous Set‐Valued Mappings

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
This paper is devoted to the various coercivity conditions in order to guarantee existence of solutions and boundedness of the solution set for the variational‐hemivariational inequalities involving upper semicontinuous operators. The results presented in this paper generalize and improve some known results.

Convergence Results for Elliptic Variational-Hemivariational Inequalities

open access: yesAdvances in Nonlinear Analysis, 2020
We consider an elliptic variational-hemivariational inequality 𝓟 in a reflexive Banach space, governed by a set of constraints K, a nonlinear operator A, and an element f.

Minimality properties of set-valued processes and their pullback attractors [PDF]

open access: yes, 2014
We discuss the existence of pullback attractors for multivalued dynamical systems on metric spaces. Such attractors are shown to exist without any assumptions in terms of continuity of the solution maps, based only on minimality properties with respect ...

Evolution of the Minimax Inequality of Ky Fan

open access: yesJournal of Operators, Volume 2013, Issue 1, 2013., 2013
There are quite a few generalizations or applications of the 1984 minimax inequality of Ky Fan compared with his original 1972 minimax inequality. In a certain sense, the relationship between the 1984 inequality and several hundreds of known generalizations of the original 1972 inequality has not been recognized for a long period.

A System of Generalized Variational‐Hemivariational Inequalities with Set‐Valued Mappings

open access: yesJournal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013
By using surjectivity theorem of pseudomonotone and coercive operators rather than the KKM theorem and fixed point theorem used in recent literatures, we obtain some conditions under which a system of generalized variational‐hemivariational inequalities concerning set‐valued mappings, which includes as special cases many problems of hemivariational ...

Existence of a nontrival solution for Dirichlet problem involving p(x)-Laplacian

open access: yes, 2014
In this paper we study the nonlinear Dirichlet problem involving p(x)-Laplacian (hemivariational inequality) with nonsmooth potential. By using nonsmooth critical point theory for locally Lipschitz functionals due to Chang and the properties of ...

Existence Results for Constrained Quasivariational Inequalities

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
We deal with a constrained quasivariational inequality under a general form. We study existence of solutions in two situations depending on whether the set of constraints is bounded or possibly unbounded.

Analysis of Stokes system with solution-dependent subdifferential boundary conditions

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2021
We study the Stokes problem for the incompressible fluid with mixed nonlinear boundary conditions of subdifferential type. The latter involve a unilateral boundary condition, the Navier slip condition, a nonmonotone version of the nonlinear Navier–Fujita
