# Insertion of Continuous Set-Valued Mappings

@inproceedings{Gutev2021InsertionOC, title={Insertion of Continuous Set-Valued Mappings}, author={Valentin G. Gutev}, year={2021} }

An interesting insertion result about the existence of “intermediate” set-valued mappings between pairs of given set-valued mappings was obtained by Nepomnyashchii. His construction was for a paracompact domain, and he remarked that his result is similar to Dowker’s insertion theorem and may represent a generalisation of this theorem. In the present paper, we characterise the τ -paracompact normal spaces by this insertion property and in the special case of τ = ω, i.e. for countably paracompact… Expand

Abstract As a rule, most of the classical Michael-type selection theorems are analogues and, in some respects, generalizations of ordinary extension theorems. In this paper we show that the existence… Expand
