    Computation of Invariants of Finite Abelian Groups Evelyne Hubert George Labahn y Ap Abstract We investigate the computation and applications of rational invariants of the linear action of a nite abelian group in the non-modular case. By diagonalization, such a group action can be described by integer matrices of orders and by: 4. polynomial generators for P(V)““’ and thus P(Y)“JtJ satisfies the splitting principle. Remark. A similar argument will show that for the dihedral groups D,,,, p z - 1 (nz) the ring of invariants P(V)“tn, with respect to the representation where y = 0 + 0 ‘.

Heavy use is made of techniques from commutative algebra, and these are developed as needed. Special attention is paid to the role. This is the first book to deal with invariant theory and the representations of finite groups. By restricting attention to finite groups Dr Benson is able to avoid recourse to the technical machinery of algebraic groups, and he develops the necessary results from commutative algebra as he proceeds.

Thus the book should be accessible to graduate students. In detail, the book. Chapter 3 discusses the polynomial invariants of finite reflection groups, and the first part ends with a description of the affine Weyl groups and the way they arise in Lie theory.

The second part (which is logically independent of, but motivated by, the first) starts by developing the properties of the Coxeter groups. Invariant theory is concerned with a group action of a group G on an algebraic variety (or a scheme) cal invariant theory addresses the situation when X = V is a vector space and G is either a finite group, or one of the classical Lie groups that acts linearly on action induces a linear action of G on the space of polynomial functions R(V) on V by the formula.

The proof is completely elementary. I was an undergraduate when I first read it and it was mystifying to me that you could do so much using so little. Polynomial invariants of finite unitary groups Article in Journal of Algebra (2) August with 18 Reads How we measure 'reads'.

The more advanced reader will find an introduction to the structure and representations of complex reductive algebraic groups and their compact real forms. This book will also serve as a reference for the main results on tensor and polynomial invariants and the finite-dimensional representation theory of the classical groups.

My only experience has been with the literature on finite (mostly real) reflection groups and their invariants, where the degrees themselves are most important for most applications.

One concrete source I should mention is the added Chapter 7 in the second edition of Grove-Benson Finite Reflection Groups ( Springer, ). Their book was. In the recently published book [11], the authors summarized the effort to determine the struc- tures of the invariant rings of all finite irreducible reflection groups.

Polynomial invariants of. This paper studies separating invariants of finite groups acting on affine varieties through automorphisms. Several results, proved by Serre, Dufresne, Kac–Watanabe and Gordeev, and Jeffries and Dufresne exist that relate properties of the invariant ring or a separating subalgebra to properties of the group by: 4.

The book, which summarizes the developments of the classical theory of invariants, contains a description of the basic invariants and syzygies for the representations of the classical groups as well as for certain other groups. One of the important applications of the methods of the theory of invariants was the description of the Betti numbers.

Broué M. () Polynomial Invariants of Finite Linear Groups. In: Introduction to Complex Reflection Groups and Their Braid Groups. Lecture Notes in Mathematics, vol Author: Michel Broué. Let G be a finite group acting linearly on the polynomial algebra $\\Bbb C [V]$. We prove that if G is the semi-direct product of cyclic groups of odd prime order, then the algebra of polynomial invariants is generated by its elements whose degree is bounded by ${5 \\over 8}|G|$.

As a consequence we derive that $\\Bbb C [V]^G$ is generated by elements of degree $\\leqq Cited by: You should trust Max Horn. Definition in our book has the finiteness condition explicitly. (This is the numbering in the first edition of the book.) For finite groups, this is equivalent to saying that the variety given by the primaries consists only of the origin (see Propos.

These are groups whose polynomial ring of invariants is a polynomial algebra. It has recently been discovered that complex reflection groups play a key role in the theory of finite reductive groups, giving rise as they do to braid groups and generalized Hecke algebras which govern the representation theory of finite reductive groups.

The book includes a dedicated chapter on graded representations and applications of polynomial invariants of finite groups, and its closing chapter addresses the more recent notion of the Drinfeld double of a finite group and the corresponding representation of GL_2(Z).

The main objects of interest in invariant theory are invariant rings of finite or algebraic groups. Polynomial invariants of knots, such as the Jones and Alexander polynomials, are constructed as quantum invariants, i.e.

invariants derived from representations of quantum groups and from the monodromy of solutions to the Knizhnik-Zamolodchikov equation. the LMO invariant, and finite type invariants of 3-manifolds are discussed.

The Chern.Let V be a complex vector space with basis {x_1,x_2,x_n} and G be a finite subgroup of GL(V). The tensor algebra T(V) over the complex is isomorphic to the polynomials in the non-commutative variables x_1, x_2, x_n with complex coefficients.
