National University of Uzbekistan named after M. Ulugbek, Tashkent

Abstract: The report is devoted to the study of cardinal and topological properties of covariant functors of finite degree. It is proved that the functor ${{\exp }_{c}}$ preserves final compactness, extremal disconnection, and an example is constructed that the functor $\exp$ does not preserve final compactness. It is also proved that the uniform hyperspace $(\exp_c X, \exp_c \mathcal{U})$ preserves precompactness, uniform locally compactness, uniform connectivity, uniform $R$-paracompactness, uniform entanglement, and uniform $P$-precompactness.
