A characterization of locally connected continua by hyperspace retractions

Author:

Nadler Sam B.

Abstract

Let X be a (metric) continuum. It is shown that X is locally connected if and only if there is special type of retraction from 2 X {2^X} onto C ( X ) C(X) , where 2 X {2^X} [resp., C ( X ) C(X) ] is the space of all nonempty compact subsets [resp., subcontinua] of X with the Hausdorff metric. Also, necessary and sufficient conditions are given for the “continuity of balls".
