Discrete Subgroups of Sl3(r) Generated by Triangular Matrices
نویسنده
چکیده
Based on the ideas in some recently uncovered notes of Selberg [14] on discrete subgroups of a product of SL2(R)’s, we show that a discrete subgroup of SL3(R) generated by lattices in upper and lower triangular subgroups is an arithmetic subgroup and hence a lattice in SL3(R).

On a Problem concerning Arithmeticity of Discrete Groups Acting
We discuss an open problem on the discreteness of subgroups of (SL2(R)) (n ≥ 2) generated by n linearly independent upper triangular matrices and n linearly independent lower triangular matrices. According to a conjecture by Margulis, only Hilbert modular groups can arise this way. The purpose of this note is to explain how this open problem is related to another conjecture on the orbit behavio...
متن کاملConvolution of Discrete Measures on Linear Groups
Let p, q ∈ R such that 1 < p < 2 and 2 p = 1 + 1q . Define ‖f‖p = max x,G1 ( ∑ y∈G1 |f(xy)|p )1/p (*) where G1 is taken in some class of subgroups specified later. We prove the following two theorems about convolutions. Theorem 2. Let G = SL2(C) equipped with the discrete topology. Then there is a constant τ = τp > 0 such that for f ∈ `(G) ‖f ∗ f‖1/2 q ≤ C‖f‖1−τ p (‖f‖p) , where the maximum in ...
متن کاملJoint and Generalized Spectral Radius of Upper Triangular Matrices with Entries in a Unital Banach Algebra
In this paper, we discuss some properties of joint spectral {radius(jsr)} and generalized spectral radius(gsr) for a finite set of upper triangular matrices with entries in a Banach algebra and represent relation between geometric and joint/generalized spectral radius. Some of these are in scalar matrices, but some are different. For example for a bounded set of scalar matrices,$Sigma$, $r_*...
متن کاملCluster Algebras I : Foundations Sergey Fomin
In this paper, we initiate the study of a new class of algebras, which we call cluster algebras. Before giving precise definitions, we present some of the main features of these algebras. For any positive integer n, a cluster algebra A of rank n is a commutative ring with unit and no zero divisors, equipped with a distinguished family of generators called cluster variables. The set of cluster v...
متن کامل2000]22e40 Property (rd) for Cocompact Lattices in a Finite Product of Rank One Lie Groups with Some Rank Two Lie Groups
We apply V. Lafforgue’s techniques to establish property (RD) for cocompact lattices in a finite product of rank one Lie groups with Lie groups whose restricted root system is of type A2. We recall that a length function on a discrete group Γ is a function l : Γ → R+ such that the neutral element is mapped to zero, and such that l(γ) = l(γ), l(γμ) ≤ l(γ) + l(μ) for any γ, μ ∈ Γ. A discrete grou...
