Abstract:
This talk will be devoted to (products of) Menger and Hurewicz spaces and
their connections to forcing and mad families. In particular, we shall show
that in the Laver model, each mad family can be destroyed by a ccc poset
preserving the ground model reals unbounded and splitting. It is an
important open problem whether the same follows from CH.
