Degree 3 Cohomological Invariants of Groups that are Neither Simply Connected nor Adjoint

  title={Degree 3 Cohomological Invariants of Groups that are Neither Simply Connected nor Adjoint},
  author={Hernando Bermudez and Anthony Michael Ruozzi},
  journal={arXiv: Group Theory},
In a recent paper A. Merkurjev constructed an exact sequence which includes as one of the terms the group of degree 3 normalized cohomological invariants of a semisimple algebraic group G, greatly extending results of M. Rost for simply connected quasi-simple groups. Furthermore, in the aforementioned paper, Merkurjev uses his exact sequence to determine the groups of invariants for all semisimple adjoint groups of inner type. The goal of this paper is to use Merkurjev's sequence to compute the… 

Invariants of degree 3 and torsion in the Chow group of a versal flag

We prove that the group of normalized cohomological invariants of degree $3$ modulo the subgroup of semidecomposable invariants of a semisimple split linear algebraic group $G$ is isomorphic to the

Chow groups of products of Severi-Brauer varieties and invariants of degree 3

We study the semi-decomposable invariants of a split semisimple group and their extension to a split reductive group by using the torsion in the codimension $2$ Chow groups of a product of

Killing Forms, W-Invariants, and the Tensor Product Map

Associated to a split, semisimple linear algebraic group G is a group of invariant quadratic forms, which we denote Q(G). Namely, Q(G) is the group of quadratic forms in characters of a maximal torus

Quadratic Forms and Related Structures over Fields

. The range of topics discussed at the workshop “Quadratic Forms and Related Structures over Fields” included core themes from the algebraic theory of quadratic and hermitian forms and their Witt

Rost Multipliers of Lifted Kronecker Tensor Products

We extend techniques employed by Garibaldi to construct various new injections involving the half-spin group, $\textbf{HSpin}$, induced by lifting the Kronecker tensor product to simply connected

Cohomological Invariants: Exceptional Groups and Spin Groups

This volume concerns invariants of G-torsors with values in mod p Galois cohomology - in the sense of Serre's lectures in the book Cohomological invariants in Galois cohomology - for various simple

Orthogonal Involutions on Algebras of Degree 16 and the Killing Form of E 8

We exploit various inclusions of algebraic groups to give a new construction of groups of type E 8 , determine the Killing forms of the resulting E 8 's, and define an invariant of central simple

Discriminant of Symplectic Involutions

We define an invariant of torsors under adjoint linear algebraic groups of type C_n-equivalently, central simple algebras of degree 2n with symplectic involution-for n divisible by 4 that takes

Orthogonal involution on algebras of degree 16 and the Killing form of E8

We exploit various inclusions of algebraic groups to give a new construction of groups of type E8, determine the Killing forms of the resulting E8's, and define an invariant of central simple

The Book of Involutions

This monograph yields a comprehensive exposition of the theory of central simple algebras with involution, in relation with linear algebraic groups. It aims to provide the algebra-theoretic

Vanishing of trace forms in low characteristics

A finite-dimensional representation of an algebraic group G gives a trace symmetric bilinear form on the Lie algebra of G. We give a criterion in terms of the root system data for this form to

Cohomological Invariants in Galois Cohomology

On Invariant Theory

In this paper it is shown how the invariants of n−ary forms can be produced from the discriminant of multilinear forms (determinants of multidimensional matricies), which should be considered as the generalization of the operation of taking classical hessians and resultants.

Decomposable and indecomposable algebras of degree $$8$$8 and exponent 2

We study the decomposition of central simple algebras of exponent 2 into tensor products of quaternion algebras. We consider in particular decompositions in which one of the quaternion algebras
