某个映象族的公共不动点定理
Common Fixed Point Theorems of a Family of Mappings

摘要: 设K是完备度量空间(x,d)的一个非空子集,f:K→K是单值映象,Fi:K→B(K)(i∈I)是一族集值映象.在某些条件下,证明了f,Fi(i∈I)在K中有唯一公共不动点存在.Abstract: Suppose K is a non-empty subset of the complete metric space (X, d), f: K → K is a singlevalued mapping, and Fi: K → B (K)(i ∈ I) are a family of set-valued mappings. Under different conditions, we prove the existence of common fixed points of f, Fi(i ∈ I) in K.
