Thin surface subgroups in cocompact lattices in SL(3,R)
Let G be a semi-simple Lie group, and Γ < G a lattice. Following Sarnak (see [19]), a finitely generated subgroup ∆ of Γ is called thin if ∆ has infinite index in Γ, but is Zariski dense. There has been a good deal of interest recently in thin groups (see for example [7], [8] and [19] to name a few), and there are many results that give credence to the statement that “generic subgroups of latti...
متن کاملInfinite Descending Chains of Cocompact Lattices in Kac-moody Groups
Let A be a symmetrizable affine or hyperbolic generalized Cartan matrix. Let G be a locally compact Kac-Moody group associated to A over a finite field Fq. We suppose that G has type ∞, that is, the Weyl group W of G is a free product of Z/2Z’s. This includes all locally compact Kac-Moody groups of rank 2 and three possible locally compact rank 3 Kac-Moody groups of noncompact hyperbolic type. ...
متن کاملRegular Coverings in Filter and Ideal Lattices
The Dedekind–Birkhoff theorem for finite-height modular lattices has previously been generalized to complete modular lattices, using the theory of regular coverings. In this paper, we investigate regular coverings in lattices of filters and lattices of ideals, and the regularization strategy–embedding the lattice into its lattice of filters or lattice of ideals, thereby possibly converting a co...

Quasi-isometric rigidity of non-cocompact S-arithmetic lattices
Throughout we let K be an algebraic number field, VK the set of all inequivalent valuations on K, and V ∞ K ⊆ VK the subset of archimedean valuations. We will use S to denote a finite subset of VK that contains V ∞ K , and we write the corresponding ring of S-integers in K as OS. In this paper, G will always be a connected non-commutative absolutely simple algebraic K-group. Any group of the fo...
