On the theorems of Y. Mibu and G. Debs on separate continuity

Using a game-theoretic characterization of Baire spaces, conditions upon the domain and the range are given to ensure a fat set C(f) of points of continuity in the sets of type X×{y}, y∈Y for certain almost separately continuous functions f:X×Y→Z. These results (especially Theorem B) generalize Mibu...

Description
Summary:Using a game-theoretic characterization of Baire spaces, conditions upon the domain and the range are given to ensure a fat set C(f) of points of continuity in the sets of type X×{y}, y∈Y for certain almost separately continuous functions f:X×Y→Z. These results (especially Theorem B) generalize Mibu's. First Theorem, previous theorems of the author, answers one of his problems as well as they are closely related to some other results of Debs [1] and Mibu [2].
