摘　　要：在一致光滑严格凸的具有对偶空间的自反Banach空间中,针对单调算子的零点逼近,提出了新的粘性迭代算法.通过定义两个单调算子确定的联合预解式,分析了该联合预解式的基本性质并推导联合预解式与常规预解式之间的关系;随后利用联合预解式构造了强单调算子与单调算子公共零点的粘性逼近序列,并在一定条件下证明了该迭代序列的强收敛性,获得了强收敛定理,同时证明了该收敛点正是某类变分不等式问题的唯一解,推广和统一了部分非线性算子类文献的结论.The viscosity iterative algorithm for the zero of monotone operators in convex closed Banach spaces with dual space is studied in this paper. In the reflexive real Banach spaces, the resolvent technique is discussed to obtain the viscosity approximation method for the zeros of monotone operators. The strong convergence theorems are proved under some appropriate conditions,at the same time, the approximated zero is exactly the solution of some variation inequality.The results have extended and unified some similar results of nonlinear operators.
