| 中文摘要: |
| 本文给出了集值映象的弱上半连续而非准上半连续的例子,证明了对于闭凸的集值映象弱上半连续和准上半连续等价,并把Kakutani不动点定理推广到非闭凸的弱上半连续的情形. |
| 英文摘要: |
| In this paper, we study the relationship between upper hemicontinuous multi- valued mappings (uhc) and upper demicontinuous multi-valued mappings (udc), we give the sim-ple example which is uhc mappings but is not udc mappings, and get kakutani's fixed point theorem for uhc mappings. |
