THURSDAYS 3:00 pm to 3:50 pm* in MS 6627/Zoom
The UCLA Mathematics Colloquium, also known as the Thursday Colloquium, is a weekly meeting featuring invited talks on diverse subjects of mathematics. The colloquium takes place usually Thursdays at 3pm and sometimes Thursdays at 4:15pm. Talks last usually around 50 minutes and are followed by questions and discussion. Many of the colloquium sessions are broadcasted live via zoom and recorded for posterity. Faculty, students, and all mathematics enthusiasts are welcome to participate in the colloquium and submit nominations of possible speakers. If you are not part of UCLA, you are still welcome to sign up to the mailing list and join the zoom sessions by following the link below.
Previous recordings can be found below.
After each talk, tea is served in the Department Lounge (MS 6620) at 4:00 pm.
The UCLA Mathematics Colloquium is supported in part by the Larry M. Weiner Mathematics Fund.
*Time subject to change based on speaker schedule or if multiple speakers are scheduled.
Thursday, December 12th, 2024 from 3:00 pm to 3:50 pm
Host: Igor Pak
Speaker: Julian Sahasrabudhe
Title: The Ramsey numbers – new results and new perspectives
Abstract.In this talk I will try to motivate the interest and some of the mystery in the Ramsey numbers R(k), which are fundamental quantities in combinatorics. I will go on to discuss some recent progress on our understanding of these numbers and make some connections to problems about the geometry of random variables in high dimensions.
