Toric ideals are binomial ideals which represent the algebraic relations of sets of power products. They appear in many problems arising from different branches of mathematics. In this paper, we develop new theories which allow us to devise a parallel algorithm and an efficient elimination algorithm

β¦ Synopsis
We address the problem of computing ideals of polynomials which vanish at a finite set of points. In particular we develop a modular Buchberger-MΓΆller algorithm, best suited for the computation over Q, and study its complexity; then we describe a variant for the computation of ideals of projective points, which uses a direct approach and a new stopping criterion. The described algorithms are implemented in CoCoA, and we report some experimental timings.

In this paper we determine the Hilbert function and the minimal system of generators of r + 1 β€ n + 1 general fat points of n . Furthermore, by looking at the minimal system of generators we can show that the ideal associated to two fat points in n or the ideal associated to r + 1 β€ n general fat po
Let K be an infinite perfect computable field and let I β K[x] be a zero-dimensional ideal represented by a GrΓΆbner basis. We derive a new algorithm for computing the reduced primary decomposition of I using only standard linear algebra and univariate polynomial factorization techniques. In practice
In this paper we show that some ideals which occur in Galois theory are generated by triangular sets of polynomials. This geometric property seems important for the development of symbolic methods in Galois theory. It may and should be exploited in order to obtain more efficient algorithms, and it e
