摘要：

We talk about the problem: for a separately continuous function f from X x Y to R, find a “big set” J in X such that f is jointly continuous at each point of J x Y (R. Baire 1899). We find some sufficient/necssary conditions for that there exists at least one point x of X such that f is jointly continuous at each point of {x} x Y.
