Title: Developments on singular Brascamp Lieb inequalities.
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.
