چکیده

The concepts of comprehensive Gröbner bases and Gröbner systems were introduced by Weispfenning in [13]. Montes in [9] has proposed DisPGB algorithm for computing Gröbner systems. But he has not explicitly used Buchberger’s criteria in his algorithm. In this paper, we show how to apply these criteria on Montes algorithm, and we propose an improved version of DisPGB.

Applying Buchberger's criteria on Montes's DisPGB algorithm

The concept of comprehensive Grobner bases was introduced by Weispfenning. Montes has proposed an efficient algorithm for computing these bases. But he has not explicitly used Buchberger's criteria in his algorithm. In this paper we prove that we can apply these criteria on Montes algorithm. We propose a modified version of Montes algorithm and evaluate its performance via some examples.

Are Buchberger's criteria necessary for the chain condition?

Buchberger’s Gröbner basis theory plays a fundamental role in symbolic computation. The resulting algorithms essentially carry out several S-polynomial reductions. In his PhD thesis and later publication Buchberger showed that sometimes one can skip S-polynomial reductions if the leading terms of polynomials satisfy certain criteria. A question naturally arises: Are Buchberger’s criteria also n...

Improving Dispgb Algorithm Using the Discriminant Ideal *

In 1992, V. Weispfenning proved the existence of Comprehensive Gröbner Bases (CGB) and gave an algorithm to compute one. That algorithm was not very efficient and not canonical. Using his suggestions, A. Montes obtained in 2002 a more efficient algorithm (DISPGB) for Discussing Parametric Gröbner Bases. Inspired in its philosophy, V. Weispfenning defined, in 2002, how to obtain a Canonical Comp...

Experimental Analysis of Involutive Criteria

In this paper we present results of our computer experiments to study effectiveness of involutive criteria for avoiding useless prolongations in construction of polynomial Janet bases. These bases are typical representative of involutive bases. Though involutive bases are usually redundant as Gröbner ones, they can be used as well as the reduced Gröbner bases in whose theory Volker Weispfenning...
