Integral norm discretization and related problems

Presented by:

Friday 21st June 2019 - 11:10 to 12:00
INI Seminar Room 1
In this talk, we will discuss the problem of replacing an integral norm with respect to a given probability measure by the corresponding integral
norm with respect to a discrete measure. We study the problem for elements of finite dimensional spaces in a general setting, paying a
special attention to the case of the multivariate trigonometric polynomials with frequencies from a finite set with fixed cardinality.
Both new results and a survey of known results will be presented.

This is a joint work with A. Prymak, V.N. Temlyakov and S. Tikhonov.
