摘要
有界闭集上的函数K<1集压缩映象是紧压缩映象,且是闭映象.有界闭凸集到自身的函数K<1集压缩映象一定有不动点.
In this paper, the followed conclusion is given: The deflation image of K set function ( K<1 ) in the bounded closed set is the compact deflation image, and also the closed image. The deflation image of K set function ( K<1 ) of the mapping in itself of the bounded closed convex set, must have the invariable points.
