摘要
文[1]证明了定义在有界闭集上的函数K<1集压缩映象是紧压缩映象,本文主要对定义在有界开集的闭包上的函数K<1集压缩映象场的拓扑度数的性质进行讨论.
Starting from proofing compressing mapping image of function (K<1) definiting on Bounded closed set is compressing closely Mapping Image. The thesis mainly discuss Topological Number proverty of compressing closely Mapping Image Field about Function (K<1) definiting on closure of bounded openset.
