“¿Qué podemos demostrar?, y ¿Qué tan grande es el infinito? Una y la misma pregunta…”
Entrentre las varias ramas de la lógica y la teoría de conjuntos, se encuentran dos que destacaremos: por un lado, el estudio acerca de aquello que es demostrable por medio de axiomas dados (como continuación de la línea de pensamiento iniciada por Hilbert e impulsada por Gödel); por otro, el estudio formal acerca de las propiedades combinatorias del infinito (descendiente directo de las indagaciones de Cantor de finales del siglo XIX). Un fenómeno muy interesante es cómo estos dos aspectos se encuentran estrechamente entrelazados: en varios casos se ha detectado que el conjunto de enunciados demostrables desde ciertos axiomas es, en un sentido técnico fuerte, más grande entre más grandes sean los tamaños del infinito que postulamos que existen. En esta plática procuraremos proporcionar algunos ejemplos históricos de este fenómeno, tanto en los niveles “bajos” de infinitud (resultados de Gentzen, Paris–Kirby, etc.) como también en los niveles más “altos” (cardinales fuertemente inaccesibles, medibles, etc.).
14:30-15:20
Dr. Atocha Aliseda Llera, IFF UNAM.
“Hacia una IA Neurosimbólica”
En esta charla presentaré prmero dos paradigmas de la IA. El primero de ellos — la IA simbólica – tiene a la lógica matemática como herramienta por excelencia. El segundo paradigma cuenta con una arquitectura de red (neuronal) y le subyacen métodos estocásticos. Si bien estos últimos han sido muy exitosos en algunos dominios, no cuentan con métodos seguros de verificación formal. ¿Es deseable usar ambos métodos? Discutiré la pertinencia de abrir la puerta a modelos híbridos en donde tanto la especificación formal como los procesos escolásticos tienen lugar.

“A Scott Analytic Perspective on Vaught’s Conjecture”
Robert Vaught conjectured that the number of countable models of any first-order theory must be either countable or continuum, but never in between. Despite all the work that has gone into this conjecture over the past sixty years, it remains open. It is one of the most well-known, long-standing open questions in mathematical logic. An interesting feature of the conjecture is that it is unclear where in logic a resolution may come from. Significant work has been produced from perspectives as varied as model theory, descriptive set theory, and computability theory. The goal of this talk is to discuss recent progress on Vaught’s conjecture and related problems coming from the field of Scott analysis. A field sitting at the intersection of descriptive set theory and computability theory, Scott analysis, has roots in the 1960s but has seen significant advances in recent years. This has allowed for promising applications to independently interesting problems like Vaught’s conjecture. The talk will begin by providing the necessary background in Scott analysis and Vaught’s conjecture before highlighting a few recent advances. This talk features joint work of the speaker with various authors, including Montalban, Rosseger, Turetsky, and Harrison-Trainor.
