Good Gradings of Simple Lie Algebras

A. G. Elashvili, V. G. Kac

Published 2003-12-10, updated 2004-12-17Version 2

We study and give a complete classification of good $\ZZ$-gradings of all simple finite-dimensional Lie algebras. This problem arose in the quantum Hamiltonian reduction for affine Lie algebras.
