Dec 10, 2021 at 9:55 comment added YCor Also, "direct product" is a group-theoretic notion, or more generally in the presence of laws to mean that the operations are taken coordinate-wise. For instance for groups, the semidirect product is a non-direct group operation on the Cartesian product. For topological spaces, I think "Cartesian product" is better suited.
Dec 10, 2021 at 7:49 comment added YCor Are you assuming the group field is $\mathbf{C}$? or $\mathbf{R}$? otherwise I'm not sure the question makes sense. Also have in mind that a real algebraic group is not exactly the same as its set of real points.
