WebA finite group generated by reflections is called a finite reflection group. A polynomial P(x) is said to be invariant under G if P(fv) =P(v) for vC EV, o-C G. Chevalley [3] has shown that the algebra I of invariants has an integrity basis consisting of n algebraically independent forms I,, * , In.

WebIn detail, the book contains an account of invariant theory for the action of a finite group on the ring of polynomial functions on a linear representation, both in characteristic zero and characteristic p. Special attention is paid to the role played by pseudoreflections, which arise because they correspond to the divisors in the polynomial ... WebThe 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 … WebDec 1, 2015 · Equivariant polynomial maps and gradients of invariants. Let G be a finite group with a linear action on C n and f ∈ C [ X 1, …, X n] be invariant. Then the gradient of f gives rise to a polynomial map ϕ from C n to C n. This map is G − equivariant, i.e., g ( ϕ ( x)) = ϕ ( g ( x)) for all g ∈ G. how many bricks should a bricklayer do a day
