### Event Description:

Title: Developments on singular Brascamp Lieb inequalities.

Abstract:

Brascamp Lieb inequalities are certain multilinear integrals that have

sparked interest in recent years. Much is understood by now on sharp Lp

bounds for such inequalities. There are oscillatory and singular variants

of Brascamp Lieb inequalities, and much remains to be undestood for

these. We focus on a method of proof called twisted technology, which

allows to prove Lp bounds for some singular Brascamp Lieb integrals.

We also discuss applications, such as to quantitative norm convergence of

bilinear ergodic averages. This is joint work with Vjekoslav Kovac,

Polona Durcik, and Kristina Skreb.
