Two talks: Aurichi and de Rancourt

The seminar meets on Wednesday February 7th at 11:00 in the Institute of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.

Program: Time permitting, we will have two talks.

  1. Leandro Aurichi — Some problems with products of Lindelöf spaces
    Some problems about the preservation of the Lindelöf property on
    products will be discussed.
  2. Noé de Rancourt — Ramsey theory with and without pigeonhole principle
    I will present an abstract infinite-dimensional Ramsey principle that doesn’t need any pigeonhole principle, and then I will compare the cases where the pigeonhole principle holds and the cases where it doesn’t, in a metamathematical way.
