Seminar on Reckoning
Wednesday, 8. March 2023 - 11:00 to 14:00

Institute of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building

We will discuss some recent results and some not-so-recent results in cardinal arithmetic and PCF theory. The precise topics will depend on the interests of the audience and the preparedness of the speaker but may include: existence theorems about PCF-theoretic scales, Silver's theorem for pseudopowers, the cov vs. pp problem, or recent work of the speaker showing that a generalized narrow system property implies Shelah's Strong Hypothesis.
