Subgroups with all finite lifts isomorphic are conjugate

Ido Karshon, Alexander Lubotzky, D. B. McReynolds +2

We show that for non-conjugate subgroups $G_{1}$ and $G_{2}$ of a finite group $G$ there exists an extension of $G$ (by a finite group) in which the pre-images of $G_{1}$ and $G_{2}$ are n…

Pro- $ℓ$ -by-cyclotomic and tamely ramified variants of the Neukirch-Uchida Theorem

Ido Karshon, Mark Shusterman

We prove a generalization of the Neukirch-Uchida Theorem. In particular, we show that the isomorphism type of a number field $K$ can be recovered from the maximal pro- $ℓ$ -by-cyc…

Annihilator varieties of distinguished modules of reductive Lie algebras

Dmitry Gourevitch, Eitan Sayag

We provide a micro-local necessary condition for distinction of admissible representations of real reductive groups in the context of spherical pairs. Let $G$ be a complex alge…
