The general concept of cleavability of mappings


M. Bonanzinga




The aim of the paper is to give some answers to the following general question: ''If $X$ and $Y$ are topological spaces and $f:X\to Y$ is a continuous mapping cleavable over the class $\mathcal P$ of topological spaces, is it true that $f$ is a $\mathcal P$-mapping?''. Answers are given for some classes of topological spaces.
