Some cardinal and topological properties of the n-permutation degree of a topological spaces and locally τ-density of hyperspaces
In the paper we investigate some cardinal and topological properties of the npermutation degree of a topological spaces and locally τ -density of hyperspaces. It is proved that the functors expn and SPn preserves locally τ -density of any infinite T1-spaces.
