Abstract

Let T:KH be a nonlinear mapping from a nonempty closed invex subset K of an infinite-dimensional Hilbert space H into H. Let f:KR be proper, invex, and lower semicontinuous on K and let h:KR be continuously Fréchet-differentiable on K with h, the gradient of h, (η,α)-strongly monotone, and (η,β)-Lipschitz continuous on K. Suppose that there exist an x*K, and numbers a>0, r0, ρ(a<p<α) such that for all t[0,1] and for all xK, the set S defined by S={(h,η):h(x+t(xx))(xx)h(x+tη(x,x)),η(x,x)} is nonempty, where K={xK:xxr} and η:K×KH is (λ)-Lipschitz continuous with the following assumptions. (i) η(x,y)+η(y,x)=0,η(x,y)=η(x,z)+η(z,y), and η(x,y)r. (ii) For each fixed yK, map xη(y,x) is sequentially continuous from the weak topology to the weak topology. If, in addition, h is continuous from H equipped with weak topology to H equipped with strong topology, then the sequence {xk} generated by the general auxiliary problem principle converges to a solution x of the variational inequality problem (VIP): T(x),η(x,x)+f(x)f(x)0 for all xK.
