Homotopy properties of subsets of Euclidean spaces
This paper is devoted to prove several results concerning the homotopy groups of separable metric spaces that generalize some of the main results of [4] and [5] to homotopy groups. In particular, we focus on subspaces of ...
On nondiscreteness of a higher homotopy group and its cardinality
Here, we are going to extend Mycielski’s conjecture to higher homotopy
groups. Also, for an (n − 1)-connected locally (n − 1)-connected compact
metric space X, we assert that ptop
n (X) is discrete if ...
On nondiscreteness of a higher homotopy group and its cardinality

On the homotopy groups of separable metric spaces
The aim of this paper is to discuss the homotopy properties of locally well-behaved spaces.
First, we state a nerve theorem. It gives sufficient conditions under which there is a weak
n-equivalence between ...
