Overspill, infinite games and forcing
Abstract: I will consider the traditional descriptive set theoretic

natural and well behaved forcing preservation property. A characterization of
overspill via a determined infinite game will be the key tool in the
proofs.

Covering omega^* by nowhere dense

"I want to mention the general problem of covering omega^* by nowhere
dense sets, but the core of the talk is about special types of coverings
(translations of nowhere dense sets by permutations of omega) and some
particular nowhere dense sets (determined by summable ideals). I intend to
emphasize the topological aspects of the problem and present
an extended general overview about nowhere dense subsets in omega^*."
