Description: We consider the problem of computing simultaneously involutive bases of an
ideal and its syzygy module. The first approach presented modifies the
classical TQ algorithm for computing Janet bases such that it also
determines a basis of the syzygy module of the Janet basis. This new
algorithm is then applied for computing Pommaret bases. The second approach
presented adapts to involutive bases a recent algorithm of Gao, Volny and
Wang (GVW) which computes in addition a basis of the syzygy module of the
input basis. |
