摘要

令E为实光滑、一致凸Banach空间, E* 为其对偶空间.令Ai,Bi \subset E × E*, i = 1,2,...,m,
为极大单调算子且∪mi=1(Ai-10∪Bi-10)≠emptyset. 引入新的迭代算法,并利用Lyapunov泛函,Qr算子与广义投影算子等技巧,证明迭代序列弱收敛于极大单调算子Ai,Bi,i =1,2,...,m的公共零点的结论.

Abstract

Let E be a real smooth and uniformly convex space with Eits duality space. For i=1,2,,m, let Ai,BiE×E be maximal monotone operators with i=1m(Ai10Bi10). A new iterative scheme is introduced which is proved to be weakly convergent to common zero points of maximal monotone operators Ai and Bi,i=1,2,,m by using the techniques of Lyapunov functionals, Qr operators, and generalized projection operators, etc.
