A binary form (of degree n) is a homogeneous polynomial Σ i=0 ( i)an−ix y = anx + ( 1)an−1x y + ... + a0y . The group SL2(C) acts on these forms by taking x to ax + by and y to cx + dy. This induces an action on the space spanned by a0, ..., an and on the polynomials in these variables. An invariant is a polynomial in these n + 1 variables a0, ..., an that is invariant under this action. More generally a covariant is a polynomial in a0, ..., an, x, y that is invariant, so an invariant is a special … WebInvariant Theory The theory of algebraic invariants was a most active field of research in the second half of the nineteenth century. Gauss’s work on binary quadratic forms, published …
WebThe first observation is that the invariant theory of binary forms of degree r can be applied to an elliptic modular form to produce in a very simple and direct way new modular forms that are expressions in the first r derivatives of the elliptic modular form. For example, the rth transvectant of a binary form of degree r produces a Rankin-Cohen WebJSTOR Home
WebJul 9, 2024 · If U is the subgroup of the upper triangular unipotent matrices, with the aid of heavy computer calculations, we know the algebra of U -invariant polynomials in K [ a 0, …, a n] only for n ≤ 10. It appears to be a hopeless task to get much further along these lines. However, it is known that after inverting the U -invariant a0, the algebra ...
WebApr 9, 2024 · In the paper, we will present some important results from the theory of vector-valued invariant means, which we will supplement with new facts previously unpublished. The formulations of the facts as well as their proofs in the case of right-hand invariance are completely analogous to the case of left-hand invariance. jeep x 350WebNov 24, 2024 · When Paul Gordan became a professor in 1875 he could show the binary form in any degree has some finite complete system of (general linear) invariants, but he could not actually give a complete system above degree 6.
