Revision as of 06:35, 10 October 2022
The Graduate Logic Seminar is an informal space where graduate students and professors present topics related to logic which are not necessarily original or completed work. This is a space focused principally on practicing presentation skills or learning materials that are not usually presented in a class.
- When: Mondays 3:30-4:30 PM
- Where: Van Vleck B139
- Organizers: Karthik Ravishankar and Antonio Nakid Cordero
The talk schedule is arranged at the beginning of each semester. If you would like to participate, please contact one of the organizers.

Fall 2022
September 12 - Organizational Meeting
We will meet to assign speakers to dates.
September 19 - Karthik Ravishankar
Title: Lowness for Isomorphism
Abstract: A Turing degree is said to be low for isomorphism if it can only compute an isomorphism between computable structures only when a computable isomorphism already exists. In this talk, we show that the measure of the class of low for isomorphism sets in Cantor space is 0 and that no Martin Lof random is low for isomorphism.
September 26 - Antonio Nakid Cordero
Title: When Models became Polish: an introduction to the Topological Vaught Conjecture
Abstract: Vaught's Conjecture, originally asked by Vaught in 1961, is one of the most (in)famous open problems in mathematical logic. The conjecture is that a complete theory on a countable language must either have countably-many or continuum-many non-isomorphic models. In this talk, we will discuss some of the main ideas that surround this conjecture, with special emphasis on a topological generalization in terms of the continuous actions of Polish groups.
October 10 - Yunting Zhang
Title: Some History of Logic
Abstract: The lives of great thinkers are sometimes overshadowed by their achievements-and there is perhaps no better illustration of this phenomenon than the life and work of Gödel. Take a look at Gödel's own timeline and see how wars and other mathematicians influenced him.
