*Title: * Arithmeticity of free-abelian by cyclic groups

*Abstract: * We discuss arithmeticity of groups G(A) = ℤ^n ⋊ ℤ, where ℤ
acts on ℤ^n by powers of an irreducible, hyperbolic matrix A ∈ GL(n,ℤ). The
question of when G(A) is arithmetic was studied systematically by
Grunewald-Platonov, but there are basic things that we still don't know.
For example, for what values of n is there an arithmetic example? We
discuss some progress toward answering this question.


See you on Thursday!

Best,

Matt
