|Title:||Cohomology of nilflows and quantitative equidistribution|
|Seminar:||Center for Dynamics and Geometry Seminars|
|Speaker:||Livio Flaminio, Lille|
|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.
