On the convergence of adaptive nonconforming finite element methods for a class of convex variational problems [PDF]

open access: yes, 2011
We formulate and analyze an adaptive nonconforming finite element method for the solution of convex variational problems. The class of minimization problems we admit includes highly singular problems for which no Euler–Lagrange equation (or inequality ...

Extended Extragradient Methods for Generalized Variational Inequalities

open access: yesJournal of Applied Mathematics, 2012
We suggest a modified extragradient method for solving the generalized variational inequalities in a Banach space. We prove some strong convergence results under some mild conditions on parameters. Some special cases are also discussed.

Regularization and Iterative Methods for Monotone Variational Inequalities

open access: yesFixed Point Theory and Applications, 2010
We provide a general regularization method for monotone variational inequalities, where the regularizer is a Lipschitz continuous and strongly monotone operator. We also introduce an iterative method as discretization of the regularization method.

Hamilton-Pontryagin Integrators on Lie Groups [PDF]

open access: yes, 2007
In this thesis structure-preserving time integrators for mechanical systems whose configuration space is a Lie group are derived from a Hamilton-Pontryagin (HP) variational principle.

Existence and concentration of solutions for the nonlinear Kirchhoff type equations with steep well potential

open access: yesBoundary Value Problems, 2017
In this paper, we study the following nonlinear problem of Kirchhoff type: { − ( a + b ∫ R 3 | ∇ u | 2 ) Δ u + λ V ( x ) u = | u | p − 2 u , in  R 3 , u ∈ H 1 ( R 3 ) , $$ \textstyle\begin{cases} - ( a + b\int_{{\mathbb{R}^{3}}} \vert {\nabla u} \vert ...

Variational methods in the presence of symmetry

open access: yesAdvances in Nonlinear Analysis, 2013
The purpose of this paper is to survey and to provide a unified framework to connect a diverse group of results, currently scattered in the literature, that can be usefully viewed as consequences of applying variational methods to problems involving ...

Self-adaptive subgradient extragradient-type methods for solving variational inequalities

open access: yesJournal of Inequalities and Applications, 2022
In this paper, we introduce two subgradient extragradient-type algorithms for solving variational inequality problems in the real Hilbert space. The first one can be applied when the mapping f is strongly pseudomonotone (not monotone) and Lipschitz ...
