Recent and upcoming talks by Andrés Caicedo
Andres Caicedo: Realvalued measurability and the extent of Lebesgue measure (II)
Thursday, November 30, 2017, from 4 to 5:30pm
East Hall, room 3096
Speaker: Andres Caicedo (Math Reviews)
Title: Realvalued measurability and the extent of Lebesgue measure (II)
Abstract:
On this second talk I begin with Solovay’s characterization of realvalued measurability in terms of generic elementary embeddings, and build on results of Judah to prove that if there is an atomlessly measurable cardinal, then all (boldface) Delta13 sets of reals are Lebesgue measurable. continue reading…
Andres Caicedo: Realvalued measurability and the extent of Lebesgue measure
Thursday, November 9, 2017, from 4 to 5:30pm
East Hall, room 3096
Speaker: Andres Caicedo (Math Reviews)
Title: Realvalued measurability and the extent of Lebesgue measure
Abstract:
The existence of an atomlessly measurable cardinal is equivalent to the existence of a measure extending Lebesgue measure and defined on all sets of reals. continue reading…
Andrés Caicedo: Realvalued measurability and Lebesgue measurable sets
University of Notre Dame, Logic Seminar • 125 HayesHealy Hall
Tue May 2, 2017 2:00PM – 3:00PM
Speaker: Andres Caicedo – Mathematical Reviews
Title: Realvalued measurability and Lebesgue measurable sets
Abstract: I will show that the existence of atomlessly measurable cardinals does not settle the range of Lebesgue measure on the projective sets. continue reading…
Andrés Caicedo: Ramsey theory and small countable ordinals
Albion College, Mathematics Colloquium
April 13, 2017, 3:30 PM
Location: Palenske 227
Speaker: Andrés Eduardo Caicedo
(Associate Editor, Mathematical Reviews, Ann Arbor, MI)
Title: Ramsey theory and small countable ordinals
Abstract: I present a brief overview of classical Ramsey theory, and discuss some extensions in the context of small infinite ordinals. continue reading…
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…
