Productively Fréchet spaces
Let \(\mathcal C\) be the class of topological spaces whose product with every strongly Fréchet space is Fréchet. An internal characterization of a member of \(\mathcal C\) is given by showing that a space is in \(\mathcal C\) if and only if every strongly Fréchet filter has a certain property.
