Spring Semester 2023 Student Probability Seminar

Welcome to the Columbia Student Probability Seminar. This seminar is the continuation of the seminar in Fall 2022. In this seminar, we will continue our studying of the Macdonald Processes. We will use the classical paper written by Alexei Borodin and Ivan Corwin. Our talks will be held in room 417 on Wednesday from 5:00 pm to 6:00 pm(EST). The first talk will start on 02/08/2023.
