Online Asymptotic Geometric Analysis Seminar


This seminar is open on Zoom for everyone who is interested to join. The seminars run on Tuesdays at 10:30am (New York, NY time) and Saturdays 11:30am (New York, NY time). If you are interested in giving a talk, please let us know. Also, please suggest speakers which you would like to hear speak. Most talks are 50 minutes, but some 20-minute talks will be paired up as well. The talks will be video recorded conditioned upon the speakers' agreement. PLEASE SHARE THE SEMINAR INFO WITH YOUR DEPRARTMENT AND ANYONE WHO MAY BE INTERESTED!

Technical aspects: preferably, you should register in Zoom; the basic account is free of charge. The easiest way to present a talk via Zoom is to make the usual slides, open them on your laptop/tablet and share your screen; alternatively, you may share your pdf via Zoom directly. If you possess a tablet with a pencil (or other writing aids), you have many more options: you may use Zoom whiteboard, which has an advantage that other participants with writing aids may also edit the same board; this may be viewed as a disadvantage, but let us hope no talks will be sabotaged:) You may alternatively share the screen and write in any writing app (such as Goodnotes), and this way you may furthermore combine slides with board writing. There are even fancier options, such as using Scribble Together app. Only the meeting host needs to have a pro account in Zoom for smooth running (which will be provided), all other participants simply need a free basic account. We will have to discover in the process if online seminars present any technical hikkups -- we shall see.

    Topic: Some new quantitative Helly-type theorems

    Abstract: Quantitative Helly-type theorems were introduced by Bárány, Katchalski and Pach in 1982, who, among other results, showed the following. There is a constant C_d depending on the dimension d only, such that if the intersection of a finite family of convex bodies in R^d is of volume at most one, then the intersection of some subfamily of 2d members is of volume at most C_d. We consider colorful and fractional versions of this result.

    Topic: John's ellipsoid of a log-concave function

    Abstract: We extend the notion of John's ellipsoid (the largest volume ellipsoid contained in a convex body) of a convex body to the setting of log-concave functions. We prove a necessary and sufficient condition for the unit ball to be the John ellipsoid of an integrable log-concave function. As an application, we prove a quantitative Helly-type result about the integral of the pointwise minimum of a family of log-concave functions. Joint work with Márton Naszódi.
