WBase: a C package to reduce tensor products of Lie algebra representations. Description and new developments

Abstract

A non trivial application of a modern computer language ("C") in a highly structured and object-oriented fashion is presented. The contest is that of Lie algebra representations (irreps), specifically the problem of reducing the products of irreps with the weight tree algorithm. The new WBase V2.0 version with table-generation and Young tableaux display capabilities is introduced.
