Abstract:
Algorithms RegSer and SimSer are improved which are presented by Wang Dongming for computing a finite set of regular/simple systems from a given set/system [P,Q] of multivariate polynomials. A new strategy for triangular decomposition is given. A series of fine triangular systems are computed such that the union of the zero sets of the fine systems is equal to that of [P, Q]. It is checked if each fine triangular system is regular. If some fine triangular system is not, a series of regular systems are computed for it. Simple systems are analogously obtained. The new algorithms are implemented in Maple, the efficiency of the routines is better than RegSer/SimSer which is shown by experimental results.
