Abstract:

In this note we prove McArthur’s conjecture [6]: If card X is nonmeasurable and if $v(X \times Y) = vX \times vY$ holds for each space Y, then X is locally compact. Consequently, we can completely characterize the class of all spaces X such that for each space Y, $v(X \times Y) = vX \times vY$ holds.
