A surjective characterization of Dugundji spaces

Author:

Hoffmann Burkhard

Abstract

It is shown that the class of Dugundji spaces coincides with the class of continuous images of the generalized Cantor set by maps satisfying the zero-dimensional lifting property. It follows that each point in a Dugundji space has a neighbourhood base of Dugundji spaces.
