For Tertulias Matemáticas (special session on Space in Mathematics and Art), together with María Clara Cortés we gave the lecture/dialogue Espacios en tensión: paisajes y procesos / Un intento de diálogo.
For the Seminario Flotante de Lógica Matemática de Bogotá, I gave the lecture On the interplay between Abstract Elementary Classes and Categorical Logic.
Abstract: I will describe two recent lines of interplay between Abstract Elementary Classes and Categorical Logic: the problem of building the “Galois group” of an AEC (building on Lascar and Poizat’s work on the “Galois theory of model theory”, and on the role of the Small Index Property – joint work of mine with Ghadernezhad) and interpreting -categoricity in terms of properties of classifying topoi (recent work of Espíndola, connected to his ground-breaking work on Shelah’s eventual categoricity conjecture). My talk will stress the way these connections appear and the opening of new lines of possibility.
During DiPriscoFest I gave the lecture Tree Partition Properties / natural logics for AEC (a tale of two cities) as homage to Carlos Di Prisco, the Caracas Logic Group and the Intertwined History of two Logic Groups: Caracas and Bogotá.
Conferencia de presentación de Fernando Zalamea para la Academia Colombiana de Ciencias Exactas, Físicas y Naturales.
A public conversation with Carlos Alberto Díez Fonnegra (Universidad Konrad Lorenz, Bogotá) on connections between Mathematics and Art. The slides were just the backdrop and source of examples. Unfortunately, the recording made by Universidad Konrad Lorenz seemed to “disappear” due to facebook’s policies.
The conversation was open to the general public and was part of a series called Conexiones Matemáticas.
For the Encuentro de Topología Carlos Ruiz (Universidad Nacional, Bogotá) I gave the lecture Cubrimientos, levantamientos y lógica matemática.
For the Coloquio de Matemáticas at Universidad Javeriana, I gave the lecture Teoría de modelos contemporánea: ¿una visión lógica de la geometría? in May of 2016.
At the Coloquio del Departamento de Matemáticas at Universidad Nacional, in Bogotá, a lecture on Sheaves, Foliations and Modular Invariantes:
