Then we prove strong convergence theorems by using a shrinking projection method. Moreover we also apply our results to a system of convex minimization problems in reflexive Banach spaces. AMS Subject Classification 47H09 47H10 Keywords Maximal monotone operator Shrinking projection method Proximal point algorithm Bregman projection Totally convex function Legendre function Introduction Let E be a real Banach space and C a nonempty subset of E. Let E be the dual space of E. We denote the value of x e E at x 2 E by fx x . Let A E 2E be a setvalued mapping. We denote dom A by domain of A that is dom A x e E Ax 0 and also denote G A by the graph of A that is G A f x x e E X E x e Ax . A set-valued mapping A is said to be monotone if fx - y x - y 0 whenever x x y y e G A . It is said to be maximal monotone if its graph is not contained in the graph of any other monotone operator on E. It is known that if A is maximal monotone then the set A -1 0 z e E 0 e Az is closed and convex. The problem of finding zero points for maximal monotone operators plays an important role in optimizations. This is because it can be reduced to a convex .
