Abstract
Let H be a real Hilbert space. Suppose that T is a nonexpansive mapping on H with a fixed point, f is a contraction on H with coefficient α∈(0,1), F:H→H is a k-Lipschitzian and η-strongly monotone operator with k>0,η>0, and A:H→H is a strongly positive bounded linear operator with coefficient γ∈(1,2). Let 0<μ<2η k2,0<γ<μ(η-μk22)α= τα. It is shown that the sequence xn generated by the following general composite iterative method: yn=(I- αnμF)Txn+αnγf( xn),xn+1=(I-βnA)Txn+ βnyn,∀n<0, where αn⊂ [0,1] and βn⊂(0,1], converges strongly to a fixed point x∈Fix(T), which solves the variational inequality 〈(I-A)x,x- x〉≤0,∀x∈Fix(T).
