凸度量空间内非扩张凝聚映象的不动点定理

FIXED POINT THEOREMS OF NONEXPANSIVE CONDENSIVE MAPS IN CONVEX METRIC SPACES

凸度量空间的闭星形子集上的非扩张凝聚多值非自映象的某些不动点定理被证明.这些定理改进和推广了 As-sad 和 Kirk,Bose 和 Mukherjee,Itoh 和 Takahashi 以及其他人的相应结果.

Some fixed point theorems of nonexpansive condensive multivalued non-self maps on closed starshaped subsets of convex metric spaces are proved.The results herein improve and extend the corresponding results of Assad and Kirk,Bose and Mukherjee,Itoh and Takahashi and others.
