| Abstract: | We prove new existence results of fixed points for upper semicontinuous multi-valued maps with not necessarily convex values. The definition domains are assumed to have the simplicial approximation property. To cite this article: Y. Askoura, C. Godet-Thobie, C. R. Acad. Sci. Paris, Ser. I 340 (2005). |
