A relaxed projection method for variational inequalities

چکیده
where S is a nonempty closed convex subset o f R ' , f is a mapp ing f rom R" into itself, and ( . , .) denotes the inner p roduc t in R n. This problem is commonly called the variational inequality problem and has proved to be very useful in dealing with a variety o f equilibrium models. As in the cases o f nonl inear equat ions and nonl inear opt imizat ion problems, solutions o f problem (1) may be obtained by utilizing an iterative method. Actually many iterative methods for solving variational inequalities have been proposed and analyzed in recent years either under a general setting [2, 3, 6-8, 15] or in the context o f specific equilibrium problems [1, 4, 5, 9-11]. As described by Pang and Chan [15] and Dafermos [6], most o f the currently available algorithms fit into the f ramework o f the following general iterative scheme: Given x k c S, determine the next iterate x k+l so as to satisfy xk+IEs, ( f k ( x k + l ) , x x k + l ) ~ o for all x c S , (2)

On the Vector Variational-like Inequalities with Relaxed η-α Pseudomonotone Mappings
In this paper we introduce some new conditions of the solu- tions existence for variational-like inequalities with relaxed &eta-&alpha pseu- domonotone mappings in Banach spaces. The advantage of these new conditions is that they are easier to be veried than those that appear in some of the previous corresponding articles.

In this paper, we introduce two concepts of weakly relaxed ${eta_gamma-alpha_gamma}_{gamma in Gamma}$ pseudomonotone and demipseudomonotone mappings in Banach spaces. Then we obtain some results of the solutions existence for a system of vector variational-like inequalities with weakly relaxed ${eta_gamma-alpha_gamma}_{gamma in Gamma}$ pseudomonotone and demipseudomonotone mappings in reflexive...
متن کاملProjection Type Method for Generalized System of Relaxed Cocoercive Variational Inequalities in Hilbert Spaces
The approximate solvability of a system of nonlinear variational inequalities involving two relaxed cocoercive mappings in Hilbert spaces is considered by exploiting projection methods. The results presented in this paper extend and improve the main results of Chang et al. [1], Verma [2, 3 ,4], Xiu and Zhang [5] and Nie et al. [6].

Recommended by Saburou Saitoh We consider a new algorithm for a generalized system for relaxed cocoercive nonlinear inequalities involving three different operators in Hilbert spaces by the convergence of projection methods. Our results include the previous results as special cases extend and improve the main results of R.
متن کاملVariational inequalities on Hilbert $C^*$-modules
We introduce variational inequality problems on Hilbert $C^*$-modules and we prove several existence results for variational inequalities defined on closed convex sets. Then relation between variational inequalities, $C^*$-valued metric projection and fixed point theory on Hilbert $C^*$-modules is studied.
