Altwaijry Najla et al., « Borsuk’s antipodal fixed points theorems for compact or condensing set-valued maps », HAL-SHS : économie et finance, ID : 10.1515/anona-2016-0128
We give a generalized version of the well-known Borsuk’s antipodal fixed point theorem for a large class of antipodally approachable condensing or compact set-valued maps defined on closed subsets of locally convex topological vector spaces. These results contain corresponding results obtained in the literature for compact set-valued maps with convex values.
