Abstract:
Suppose that is a Hausdorff space such that its Vietoris hyperspace has a continuous selection. Do disconnectedness-like properties of depend on the variety of continuous selections for and vice versa? In general, the answer is ``yes'' and, in some particular situations, we were also able to set proper characterizations.
