摘要: In this paper the fixed pansy stems theorems concerning the composition-complement-operators are discussed. Some existence conditions of panchaos and strange panat tractor are given. And using the results, some fixed point theorems for many-valued mappings are also proved, which complement and develop the results obtained by Kakutani.
