Τίτλος: Very weak solutions to PDEs with singularities

Abstract: In this talk we will review the notion of very weak solutions, introduced for dealing with PDEs with very strong singularities in coefficients or data.

Τίτλος: Discrete entropy monotonicity for log-concave sums on Z and Z^d

Περίληψη: A celebrated result of Artstein, Ball, Barthe and Naor (2004) states that the differential entropy of sums of continuous random variables increases along the central limit theorem. Although an exact analogue of this statement cannot be true for discrete random variables, Tao (2010) conjectured that an approximate version is true provided that the underlying entropies are large enough. We will present a recent proof of a special case of this conjecture for log-concave random variables on the integers and discuss current progress towards extending this result on Z^d. For the dimensional extension, we will mention some discrete analogues of results from convex analysis that may be of independent interest.

Part of the talk is based on joint work with M. Fradelizi and M.  Rapaport.

5th Summer School MATH@NTUA: “Mathematics of Machine and Statistical Learning”

The Department of Mathematics of the School of Applied Mathematical and Physical Sciences in the National Technical University of Athens (NTUA) is organising the 5th MATH@NTUA summer school titled

Mathematics of Machine and Statistical Learning

The school will take place from 19 to 23 June 2023 at the Zografou Campus of the NTUA in Athens, Greece. The targeted audience is senior undergraduate, MSc and PhD students  interested in the mathematical aspects of machine and statistical learning.

The school consists of four mini-courses that will be given by

Constantine Caramanis (University of Texas, Austin, USA)

Daniele Durante (Universitá Bocconi, Milano, Italy)

Panayotis Mertikopoulos (National & Kapodistrian University of Athens)

Konstantinos Spiliopoulos (Boston University, USA)

The lectures will be complemented by hands-on programming seminars.
