Speaker: Robert Rałowski
Title: Mycielski among trees - nonstandard proofs
Abstract. We present proofs of Mycielski like Theorem for sigma ideal of meager subsets of Baire space and Egglestone like Theorem. In both proofs we use Schoenfield Absolutness Theorem. In Mycielski Theorem we replace the term perfect set by slalom perfect set what is some strengthen of the classical version. Results are from common paper with Marcin Michalski and Szymon Żeberski.
