Title of program: LEVI
Catalogue Id: AAXN_v1_0
Nature of problem
Given a Lie algebra L with structure constants which are either integers or polynomials with integer coefficients, LEVI determines a LEVI decomposition of L into its radical R(L) and its (semi-)simple part S(L). The program CANONIK uses the methods of all three programs SPLIT, LEVI and RADICAL in order to express L in a standard basis: L is decomposed as a direct sum, each component L' is Levi-decomposed, each S(L') is decomposed as a direct sum, the nilradical of each r(l') is calculated, and f ...
