CONTRACTIONS

The computer calculation of graded contractions of Lie algebras and their representations. We present a computer program to generate and solve the defining equations for grading preserving contractions of Lie algebras of any type, and their representations. The algorithm applies to any grading semigroup which is finite and abelian. It can perform contractions of Lie algebras and/or representations for which the grading is either generic or not. (The program is obtainable via Internet-ftp: genesis.ulaval.ca).
