Description

Title of program: SPLIT Catalogue Id: AAXM_v1_0 Nature of problem Given a Lie algebra L with structure constants which are either integers or polynomials with integer coefficients, SPLIT determines whether L can be expressed as a direct sum of Lie algebras of smaller dimension and, if so, calculates the structure constants of its components. Versions of this program held in the CPC repository in Mendeley Data AAXM_v1_0; SPLIT; 10.1016/0010-4655(87)90006-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
