We announce the approximation-solvability of the following class of nonlinear variational inequality (NVI) problems based on a new generalized auxiliary problem principle:
Find an element such that
for all
where is a mapping from a nonempty closed convex subset of a real Hilbert space into , and is a continuous convex functional on .
The generalized auxiliary problem principle is described as follows: for a given iterate and, for constants and , compute such that
, for all and for , where
for all where is twice Frechet-differential functional on .
Theorem: Let be a real Hilbert space and a - -partially relaxed mono- tone mapping from a nonempty closed convex subset of into . Let be twice continuous Frechet-differentiable on with the following assumptions
and
Then for any fixed solution of the NVI problem, the sequence ! is bounded and converges to for
