Proximal point | equilibrium problem | Maximal monotone operators | variational inequalities
We propose and analize a proximal point method for equilibrium problems in Hilbert spaces, which extends the well known proximal point method for variational inequalities. We prove global weak convergence of the generated sequence to a solution of the problem, assuming existence of solutions and rather weak monotonicity properties of the bifunction f which defines the equilibrium problem. We also present a reformulation of equilibrium problems as variational inequalities, under the same assumptions on f.
