  • In this paper, we establish existence theory and algorithms on
    variational problems, by which we mean here problems of fixed
    points, coincidences, minimax inequalities, generalized variat-
    ional inequalities, generalized quasi-variational inequalities.
    Under weakened assumptions on the operators and constraint reg-
    ions, we improve and generalize recently many well-known exist-
    ence theorems. More specifically, we establish two versions of
    Nikaidos coincidence theorem from different approaches, and use
    these to show several existence theorems for the generalized v-ariational inequalities, in the case that C is noncompact and
    nonconvex, but merely a nearly convex set. Also, we introduce
    a new Bregman-type proximal point algorithm for solving variat-
    ional inequalitiy problems in a reflexive Banach space, and pr-
    ovide a continuation method to solve nonsmooth convex programm-
    ing.
