半序度量空间中单调减映射的不动点定理

Partially oydered metric space and fixed point theorem of decreasing operator

利用[1]在度量空间中引入的半序,证明了半序度量中单调减映射的不动点定理,并给出了迭代及其收敛性.

In this paper we prove the theorem that decreasing operator has a fixed point in the partially ordered space by using parial ordering“≤”given in the paper〔1〕and give the interia sequences and the property ofconvergence.
