Decidability, Definability, and Computability in Number Theory
DDC Junior Seminar
Tuesdays at 9:00am Pacific Time
Organizers: Russell Miller, Lynn Scow, and Meng-Che "Turbo" Ho
The seminar will feature research talks by the six postdoctoral scholars appointed to the Fall 2020 DDC program, along with talks by students and other pre-tenure researchers associated with this program. Since seminar attendees will have disparate backgrounds, we plan that these talks will not be too advanced, nor will they assume substantial background knowledge. Our postdocs include number theorists, model theorists, and computable structure theorists, and talks can be expected to span all of these areas.
