On the spectral theory of groups of automorphisms of $S$ -adic nilmanifolds

Bachir Bekka, Yves Guivarc'h

Let $S = {p_{1}, \dots, p_{r}, \infty}$ for prime integers $p_{1}, \dots, p_{r} .$ Let $X$ be an $S$ -adic compact nilmanifold, equipped with the unique translation invariant probability meas…

Spectral gap property and strong ergodicity for groups of affine transformations of solenoids

Bachir Bekka, Camille Francini

Let X be a solenoid, that is, a compact finite dimensional connected abelian group with normalized Haar measure m, and let G be a countable discrete group acting on X by continuous…
