Abstract: The main theorem of this paper is somewhat stronger than the following statement: Let $G$ be a Baire semitopological group, let $H$ be a first countable one and let $N$ be a first countable topological group; then each separately continuous bi-homomorphism from $G\times H$ into $N$ is jointly continuous. This theorem has some consequences on joint continuity of separately continuous multiplication of rings and scalar multiplication of modules.
