Browder集值映象不动点定理的推广和应用

The Generalization and Application of Browder's Fixed Point Theorem of Set-valued Mapping

本文应用转移开和转移闭映象概念首先对Ｂｒｏｗｄｅｒ集值映象不动点定理进行了推广，然后应用所得结果研究了截口定理和社会平衡问题解的存在性。

In this paper, applving the concepts of the transfer opermess and transfer closedness, the Browder's fixed point theorem of set-valued mapping is first gen eralized, then the section theorem and the social equilibrium problem are studied byusing the generalization of the Browder' S fixed POint theorem.
