Cohomological invariants in Galois cohomology, by Skip Garibaldi, Alexander
Quadratic forms q(x1, . . . , xn) over a field k are the classical examples of nonlinear scalar-valued functions on a vector space V = k, and they lie at the foundation of nineteenth-century analytic geometry. Motivated by problems such as finding the axes of a conic, geometers studied quadratic forms under symmetries of V . Given two quadratic forms q, q′ on V , how may we tell if q and q′ are...
متن کاملComplexity and cohomology of cohomological Mackey functors
Let k be a field of characteristic p > 0. Call a finite group G a poco group over k if any finitely generated cohomological Mackey functor for G over k has polynomial growth. The main result of this paper is that G is a poco group over k if and only if the Sylow p-subgroups of G are cyclic, when p > 2, or have sectional rank at most 2, when p = 2. A major step in the proof is the case where G i...
متن کاملCohomological Finiteness Conditions in Bredon Cohomology
We show that soluble groups G of type Bredon-FP∞ with respect to the family of all virtually cyclic subgroups of G are always virtually cyclic. In such a group centralizers of elements are of type FP∞. We show that this implies the group is polycyclic. Another important ingredient of the proof is that a polycyclic-by-finite group with finitely many conjugacy classes of maximal virtually cyclic ...
متن کاملAlgorithmic Computation of Local Cohomology Modules and the Cohomological Dimension of Algebraic Varieties
In this paper we present algorithms that compute certain local cohomology modules associated to a ring of polynomials containing the rational numbers. In particular we are able to compute the local cohomological dimension of algebraic varieties in characteristic zero.
متن کاملGalois Module Structure of Galois Cohomology
Let F be a field containing a primitive pth root of unity, and let U be an open normal subgroup of index p of the absolute Galois group GF of F . We determine the structure of the cohomology group H(U, Fp) as an Fp[GF /U ]-module for all n ∈ N. Previously this structure was known only for n = 1, and until recently the structure even of H(U, Fp) was determined only for F a local field, a case se...
