The sentence "What algebraic conditions on $A$ and/or $B$ ensure that the homomorphism $\theta$ is automatically continuous?" is a little confusing to the non-expert. It suggests that there is some special form of continuity called "automatic continuity", in the same way that one speaks of "uniformly continuous", for example. It would help the general reader to write, for example "$\ldots\ \theta$ is <u>necessarily</u> continuous", as Garth Dales does in the introduction to his 1978 survey paper.

The sentence "What algebraic conditions on $A$ and/or $B$ ensure that the homomorphism $\theta$ is automatically continuous?" is a little confusing to the non-expert. It suggests that there is some special form of continuity called "automatic continuity", in the same way that one speaks of "uniformly continuous", for example. It would help the general reader to write, for example "$\ldots\ \theta$ is __necessarily__ continuous", as Garth Dales does in the introduction to his 1978 survey paper.
