Wednesday, September 24 from 3 to 4pm
Room: Math 226
Speaker: Andrés Caicedo (BSU)
Title: Ramsey theory of very small countable ordinals

Abstract: We present a brief introduction to classical Ramsey theory, and discuss two extensions in the context of ordinals. We limit ourselves to small countable ordinals, emphasizing those smaller than $\omega^2$.
