Homotopical properties of upper semifinite hyperspaces of compacta
چکیده انگلیسی

In this paper we study homotopical properties of a special neighborhood system, which is denoted by {Uε}ϵ>0, for the canonical embedding of a compact metric space in its upper semifinite hyperspace to get results in the shape theory for compacta. We also point out that there are spaces with the shape of finite discrete spaces and having not the homotopy type of any T1-space
