Márton Naszódi "John ellipsoid for log-concave functions"
Márton Naszódi (Combinatorial Geometry Research Group and Dept. of Geometry, Loránd Eötvös Univ., Budapest, Hungary) will give the talk "John ellipsoid for log-concave functions" on the labs' Big Seminar.
Password: first 6 decimal places of $\pi$ after the decimal point
We extend the notion of the largest volume ellipsoid contained in a convex body to the setting of log-concave functions. 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 Grigory Ivanov.
Everyone is invited to attend. The language of the lecture is English. The event is aimed at master and graduate students, as well as researchers in the field of combinatorics.
