Attractors for Navier-Stokes flows with multivalued and nonmonotone subdifferential boundary conditions

, 2014
We consider two-dimensional nonstationary Navier-Stokes shear flow with multivalued and nonmonotone boundary conditions on a part of the boundary of the flow domain.

Existence and comparison results for variational-hemivariational inequalities

Journal of Inequalities and Applications, 2005
We consider a prototype of quasilinear elliptic variational-hemivariational inequalities involving the indicator function of some closed convex set and a locally Lipschitz functional.

Tykhonov well-posedness of elliptic variational-hemivariational inequalities

Electronic Journal of Differential Equations, 2019
We consider a class of elliptic variational-hemivariational inequalities in an abstract Banach space for which we introduce the concept of well-posedness in the sense of Tykhonov.

Risultati di esistenza per alcune classi di disequazioni variazionali-emivariazionali di tipo ellittico

Le Matematiche, 2005
The main purpose of this lecture is to present some basic notions on variational and variational-hemivariational inequalities as well as two recent existence results in the elliptic case. A wide bibliography is also provided.

On the Convergence of (Stochastic) Gradient Descent with Extrapolation for Non-Convex Optimization

, 2019
Extrapolation is a well-known technique for solving convex optimization and variational inequalities and recently attracts some attention for non-convex optimization. Several recent works have empirically shown its success in some machine learning tasks.

Infinitely many solutions via variational-hemivariational inequalities under Neumann boundary conditions

Electronic Journal of Differential Equations, 2016
In this article, we study the variational-hemivariational inequalities with Neumann boundary condition. Using a nonsmooth critical point theorem, we prove the existence of infinitely many solutions for boundary-value problems.

Existence of projected solutions for quasi-variational hemivariational inequality

Demonstratio Mathematica
In this short article, we prove the existence of projected solutions to a class of quasi-variational hemivariational inequalities with non-self-constrained mapping, which generalizes the results of Allevi et al.

The Dirichlet problem for discontinuous perturbations of the mean curvature operator in Minkowski space [PDF]

, 2015
Using the critical point theory for convex, lower semicontinuous perturbations of locally Lipschitz functionals, we prove the solvability of the discontinuous Dirichlet problem involving the operator $u\mapsto{div} (\frac{\nabla u}{\sqrt{1-|\nabla u|^2}})
