摘要
We introduce the notion of categorical cliquish mapping and show that, for each K (h) C-mapping f: X x Y -> aEuro parts per thousand Z, where X is a topological space, Y is a space with the first axiom of countability, and Z is a Moore space, with categorical-cliquish horizontal y-sections f (y) , the sets C (y) (f) are residual G (delta)-type sets in X for every y a Y.
