Weak Convergence Theorems for Maximal Monotone Operators with Nonspreading mappings in a Hilbert space
Hiroko Manaka, Wataru Takahashi · Cubo · 2011
Let C be a closed convex subset of a real Hilbert space H. Let T be a nonspreading mapping of C into itself, let A be an α-inverse strongly monotone mapping of C into H and let B be a maximal monotone operator on H such that the domain of B is included in C. We introduce an iterative sequence of finding a point of F (T )∩(A+B) -1 0, where F (T ) is the set of fixed points of T and (A + B) -1 0 is the set of zero points of A + B. Then, we obtain the main result which is related to the weak convergence of the sequence.Using this result, we get a weak convergence theorem for finding a common fixed point of a nonspreading mapping and a nonexpansive mapping in a Hilbert space.Further, we consider the problem for finding a common element of the set of solutions of an equilibrium problem and the set of fixed points of a nonspreading mapping.
