Recent and upcoming talks by Andrés Caicedo
Andrés Caicedo: The HaddadSabbagh results in the partition calculus of small countable ordinals
Wednesday, October 7, 16:00 to 17:30 in 3096 East Hall
We present a survey of results announced 45 years ago by Haddad and Sabbagh on the partition calculus of ordinals. Part of the interest in these results is that they are obtained by reducing genuine infinitary combinatorics problems to purely finite (albeit unfeasible) ones. continue reading…
Andrés Caicedo: Topological partition properties of $\omega_1$, part II
Wednesday, January 28 from 3 to 4pm
Room: Math 124
Speaker: Andrés Caicedo (BSU)
Title: Some topological partition properties of $\omega_1$, part II
Abstract: We discuss some new results on the topological partition calculus of ordinals less than or equal to $\omega_1$. continue reading…
Andrés Caicedo: Topological partition properties of $\omega_1$
Wednesday, January 21 from 3 to 4pm
Room: Math 124
Speaker: Andrés Caicedo (BSU)
Title: Some topological partition properties of $\omega_1$
Abstract: I present some classical and new positive results on the topological version of partition relations involving $\omega_1$. continue reading…
Andrés Caicedo: Coanalytic uniformization
Wednesday, December 10 from 3 to 4pm
Room: Math 226
Speaker: Andrés Caicedo (BSU)
Title: Coanalytic uniformization
Abstract: It is an easy consequence of the axiom of choice that if X is an arbitrary set and R is a binary relation on X (a subset of $X^2$) then R admits a uniformization, that is, there is a function f whose domain is $\{x \in X : \text{there is a } y \in X \text{ with } x R y\}$ and such that for all x in its domain, x R f(x). continue reading…
Andres Caicedo: Ramsely theory of very small countable ordinals II
Wednesday, October 1 from 3 to 4pm
Room: Math 226
Speaker: Andrés Caicedo (BSU)
Title: Ramsey theory of very small countable ordinals II
Abstract: We examine a closed version of the pigeonhole principle for ordinals, and use it to draw upper bounds on closed Ramsey numbers. continue reading…
Andrés Caicedo: Ramsey theory of very small countable ordinals
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. continue reading…
Andrés Caicedo: An absoluteness result
Tuesday, February 18 from 2 to 3pm
Room: Mathematics 136
Speaker: Andrés Caicedo (BSU)
Title: An absoluteness result
Abstract: We present examples of some (Ramseytheoretic) theorems of ZFC (whose standard proofs make blatant use of choice) that can be established in ZF as well. continue reading…
Andrés Caicedo: Second incompleteness
Monday, October 7 from 3 to 4pm
Room: Mathematics 136
Speaker: Andrés Caicedo (BSU)
Title: Second incompleteness
Abstract: We sketch an essentially model theoretic proof (due to
Woodin) of the second incompleteness theorem for ZF. continue reading…
Andrés Caicedo: Finitary mathematics
Thursday, February 21 from 1:30 to 2:30pm
Room: B309
Speaker: Andrés Caicedo
Title: Finitary mathematics
Abstract: $\mathsf{ZF}_{\mathsf{fin}}$ is the standard formalization of finitary mathematics; it replaces the axiom of infinity in $\mathsf{ZF}$ with its negation. continue reading…
Andres Caicedo: Determinacy from large cardinals II
Boise Set Theory Seminar
Thursday, February 7
Room: B309
Speaker: Andrés Caicedo (Boise State)
Title: Determinacy from large cardinals: an overview II
Abstract:
We recall the definition of Woodin cardinals, and explain why they play a key role in proofs of determinacy. continue reading…
