Conditions involving sequences of continuous maps and functionally ambiguous sets.
Abstract
We introduce and study adhesive spaces. Using this concept we obtain a characterization of stable Baire maps of the class for wide classes of topological spaces. In particular, we prove that for a topological space and a contractible space a map belongs to the 'th stable Baire class if and only if there exist a sequence of continuous maps and a sequence of functionally ambiguous sets of the 'th class in such that for every . Moreover, we show that every monotone function is of the 'th stable Baire class if and only if it belongs to the first stable Baire class.
