Finiteness properties of soluble arithmetic groups over global function fields
Let G be a Chevalley group scheme and B ≤ G a Borel subgroup scheme, both defined over Z. Let K be a global function field, S be a finite non-empty set of places over K , and OS be the corresponding S–arithmetic ring. Then, the S– arithmetic group B(OS) is of type F |S|−1 but not of type FP |S| . Moreover one can derive lower and upper bounds for the geometric invariants Σ(B(OS)). These are sha...
متن کاملArithmetic over Function Fields
These notes accompany lectures presented at the Clay Mathematics Institute 2006 Summer School on Arithmetic Geometry. The lectures summarize some recent progress on existence of rational points of projective varieties defined over a function field over an algebraically closed field.
متن کاملFiniteness properties of arithmetic groups over function fields
We determine when an arithmetic subgroup of a reductive group defined over a global function field is of type FP∞ by comparing its large-scale geometry to the large-scale geometry of lattices in real semisimple Lie groups.
متن کاملOn Generators of Arithmetic Groups over Function Fields
Fq = the finite field with q elements; throughout the paper q is assumed to be odd. A = Fq[T ], T indeterminate. F = Fq(T ) = the fraction field of A. |F | = the set of places of F . For x ∈ |F |, Fx = the completion of F at x. Ox = {z ∈ Fx | ordx(z) ≥ 0} = the ring of integers of Fx. Fx = the residue field of Ox; deg(x) = [Fx : Fq]. For 0 = f ∈ A, deg(f) = the degree of f as a polynomial in T ...
