Abstract

I will discuss the Poisson bracket invariant of a cover, which was introduced by L. Polterovich.

Initially, this invariant was studied via Floer theory, and lower bounds for it were established in

some situations. I will try to explain how one can obtain the conjectural lower bound in dimension 2, using only elementary arguments. This is a joint work with A. Logunov and S. Tanny, with a

contribution of F. Nazarov.
