Resumo

We say that a space X is selectively pseudocompact if for each sequence (U-n)(n<omega) of nonempty open subsets of X there is a sequence (x(n))(n<omega) of points in X such that xn is an element of U-n, for each n < omega, and the set [x(n) : n < omega] has a cluster point in X. We prove that if p and q are not equivalent selective ultrafilters on omega, then there are a p-compact group and a q-compact group whose product is not selectively pseudocompact.
