报告摘要：

This talk is a self-contained exposition of aspects of the “substantial” joint continuity of separately continuous functions f : X × Y → Z. Importantly, it also includes some new elements and improvements of some classical theorems. In particular, if G is a semitopological group and a G-action f : G × X → X is not to be assumed continuous, then we find conditions on G and X so that f is jointly continuous and G is a Baire topological group.
