Title

Mappings and Spaces Defined by the Function Epsilon

Abstract

The function εX assigns to each point of a given continuum X the closure of the family of all continua that contain x in their interior. We define the class S(ε) of continua for which the function εX is continuous. On the other hand, we consider some natural diagram involving the function εX and commutativity of this diagram defines a class of mappings M(ε). We investigate classes S(ε) and M(ε), and relations between them.
