The Columbia Undergraduate Learning Seminar in Theoretical Computer Science is a student-run seminar for undergraduates at Columbia interested in theoretical computer science. The goal of the learning seminar is to provide undergraduate students with the opportunity to learn about theoretical computer science in a collaborative, student-driven setting and to meet other students interested in theoretical computer science.
The learning seminar is dedicated to providing an inclusive and welcoming environment for all students interested in theoretical computer science. No background in theoretical computer science is required to participate in the seminar, and everyone is welcome to join!
Each semester, the Columbia Undergraduate Learning Seminar in Theoretical Computer Science will hold one or more seminars on topics related to TCS. The presentations will primarily be given by students, which is a great opportunity to gain experience giving a technical talk in TCS.
During Summer 2021, we will be holding four groups, each focused on a different topic within TCS. The groups are: NP-Completeness, Analysis of Boolean Functions and Property Testing, Algorithmic Game Theory, and Computational Learning Theory. Each group is run by an undergraduate student organizer and a graduate student mentor. The groups meet weekly and should be approachable for students of all ranges of prior exposure to TCS.
Please see the descriptions and tables below for a summary and the list of talks for each of the groups.

Description: We will focus on the study of various notions of equilibria in game theory with an emphasis on the computational tractability of finding equilibria. We also study the price of anarchy, connections between game dynamics (learning in games) and equilibria, and recent notions of solution concepts for games that go beyond classic notions of equilibria.
