Title : Infinite games and sigma-porosity
Speaker: Martin Dolezal
Affiliation: Czech Academy of Sciences
Time: 1:00 pm Friday, 9 September, 2016
Location: 303S-Room 561
We introduce an infinite game characterizing various types of sigma-porosity for Souslin sets in terms of winning strategies. We use the game to prove and reprove some new and older inscribing theorems for sigma-ideals of sigma-porous type in locally compact metric spaces. This is based on a joint work with D. Preiss and M. Zelený.
