Commensurators of solvable S-arithmetic groups

Daniel Studenmund

We show that the abstract commensurator of an S-arithmetic subgroup of a solvable algebraic group over Q is isomorphic to the Q-points of an algebraic group, and compare this with…

Abstract commensurators of lattices in Lie groups

Daniel Studenmund

Let Gamma be a lattice in a simply-connected solvable Lie group. We construct a Q-defined algebraic group A such that the abstract commensurator of Gamma is isomorphic to A(Q) and…
