摘要
证明了以下结论:若T是巴拿赫空间X中的闭凸子集D到紧致子集D中的不放大映射,且x1是D中任一点,那么由xn+1=2-1(xn+Txn)所表示的序列{xn}收敛于T的不动点,并由此得到了两个推论.
The following result is shown:If T is a nonexpansive mapping from a closed convex subset D of a Banach space into a compact subset of D and x1 is any point in D,then the sequence {xn} defined by xn+1=2-1(xn+Txn) converges to a fixed point of T,and two conresponding corollaries are given.
