WebbX Y is not the product topology: e.g. the subset V(x 1 x 2) = f(a;a) : a 2KgˆA2 is closed in the Zariski topology, but not in the product topology of A1 A1. In fact, we will see in Proposition4.10that the Zariski topology is the “correct” one, whereas the product topology is useless in algebraic geometry.

We consider the binary supremum function \sup :Z\times Z\rightarrow Z on a sup semilattice Z and its topological properties with respect to the Scott topology and the product topology. It is well known that this function is continuous with respect to the Scott topology on Z\times Z. We show that it is open as well.
