Abstract
The path component space of a topological space is the quotient space whose points are the path components of . We show that every Tychonoff space is the path-component space of a Tychonoff space of weight such that the natural quotient map is a perfect map. Hence, many topological properties of transfer to . We apply this result to construct a compact space for which the fundamental group is an uncountable, cosmic, -topological group but for which the canonical homomorphism to the first shape homotopy group is trivial.
