Recent and upcoming talks by Andrés Caicedo
Andres Caicedo: MRP and squares, II
Thursday, March 23, 2017, from 4 to 5:30pm
East Hall, room 3088
Speaker: Andres Caicedo (Math Reviews)
Title: MRP and squares, II
Abstract:
Justin Moore’s mapping reflection principle (MRP) seems to capture the consistency strength of PFA, since it implies the failure of square. continue reading…

Andres Caicedo: Preserving sequences of stationary subsets of omega_1
Thursday, November 10, 2016, from 4 to 5:30pm
East Hall, room 3096
Speaker: Andres Caicedo (Math Reviews)
Title: Preserving sequences of stationary subsets of omega_1
Abstract:
Let M be an inner model that computes omega_1 correctly. continue reading…
Andrés Caicedo: Topological partition calculus of countable ordinals
Thursday, April 14, 2016; 4:005:30 PM, in East Hall 2866.
This is joint work with Jacob Hilton. We considered the topological version of the partition calculus in the setting of countable ordinals: Given ordinals $\alpha,\beta_0,\beta_1$, we say that $\alpha\to_{top}(\beta_0,\beta_1)^2$ iff for any 2coloring of the edges of the complete graph on $\alpha$ vertices, for some color $i$, there is a complete monochromatic graph in color $i$ whose set of vertices is homeomorphic to $\beta_i$. continue reading…
Andrés Caicedo: The HaddadSabbagh results in the partition calculus of small countable ordinals, II
Thursday, October 22, 1015 — 16:00 to 17:30 — East Hall 3096
We present the second part of a survey of results announced 45 years ago by Haddad and Sabbagh on the partition calculus of ordinals. continue reading…
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…
