Title:Cohomology of nilflows and quantitative equidistribution
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Livio Flaminio, Lille
Abstract:
A nilflow is the flow generated by a one-parameter subgroup of a nilpotent (connected, simply connected) Lie group $N$ on a compact quotient $N/\Gamma$. Their dynamical cohomology is perfectly understood in terms of harmonic analysis. It is well know that the equidistribution of nilflows is connected with the equidistribution of polynomial sequences mod 1. In some particular cases, quantitative estimates for the equidistribution of these flows can be obtained by studying the action of a suitable rescaling on the space of flow-invariant distributions.
