The function 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 of continua for which the function is continuous. On the other hand, we consider some natural diagram involving the function and commutativity of this diagram defines a class of mappings . We investigate classes and , and relations between them.
