Abstract
In a recent paper, it was shown that the problem of existence of a continuous map extending a given map defined on a subspace is undecidable, even for an even-dimensional sphere. In the present paper, we prove that the same problem for an odd-dimensional sphere is decidable. More generally, the same holds for any -connected target space whose homotopy groups are finite for .
