SUMMARY
The discussion centers on the path connectedness of the union of a collection of path connected subspaces {Aj} within a space X, given that their intersection is nonempty. The conclusion drawn is that the union U Aj is not necessarily path connected in general. However, the presence of a nonempty intersection implies that any two points, x from U Aj and y from the intersection, can be connected by a path, as both points belong to at least one common subspace Aj.
