For Invariants of Small Matrices 3
نویسندگان
چکیده
We determine explicit denominators for the Poincar e series of (a) the invariants of m generic N N matrices, and (b) the ring generated by m generic N N matrices and their traces, for N 4. For N 3 we prove (and for N = 4 we conjecture) that the denominators we obtain are of minimum degree. We also give explicit rational fractions for both series for small values of m and N.

A Complete Set of Unitary Invariants for 3x3 Complex Matrices
is a complete set of unitary invariants for any wX» complex matrix A. The author was able to improve this result by demonstrating in [3] that for re fixed but arbitrary, there is always a subset of the above collection containing fewer than 24" traces which serves as a complete set of unitary invariants for «X» matrices. It is of interest to discover the sharpness of the above upper bound on th...
متن کاملNew Algorithm For Computing Secondary Invariants of Invariant Rings of Monomial Groups
In this paper, a new algorithm for computing secondary invariants of invariant rings of monomial groups is presented. The main idea is to compute simultaneously a truncated SAGBI-G basis and the standard invariants of the ideal generated by the set of primary invariants. The advantage of the presented algorithm lies in the fact that it is well-suited to complexity analysis and very easy to i...
متن کاملPolynomial degree bounds for matrix semi-invariants
We study the left-right action of SL n × SL n on m-tuples of n × n matrices with entries in an infinite field K. We show that invariants of degree n 2 − n define the null cone. Consequently, invariants of degree ≤ n 6 generate the ring of invariants if char(K) = 0. We also prove that for m ≫ 0, invariants of degree at least n⌊ √ n + 1⌋ are required to define the null cone. We generalize our res...

متن کاملOn minimal generating systems for matrix O(3)-invariants
The algebra of invariants of several 3×3 matrices under the action of the orthogonal group by simultaneous conjugation is considered over a field of characteristic different from two. The maximal degree of elements of minimal system of generators is described with deviation 3. 2000 Mathematics Subject Classification: 16R30; 13A50.
