Kronecker indices of the Lie algebra and an estimate for the degrees of invariants
A. S. Vorontsov Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
The notion of Kronecker indices of a Lie algebra as integers naturally connected to its structure tensor is introduced. A lower bound for the degrees of polynomial invariants of the coadjoint action in terms of Kronecker indices is proved.
Key words:
Lie algebra, coadjoint representation, invariants, bi-Hamiltonian geometry.
