Eisenstein series and equidistribution of Lebesgue probability measures on compact leaves of the horocycle foliations of Bianchi 3-orbifolds

Otto Romero, Alberto Verjovsky

Inspired by the works of Zagier, we study the probability measures $\nu (t)$ with support on the flat tori which are the compact orbits of the maximal unipotent subgroup acting holomo…
