摘要
The effective computation of resultants of multivariate polynomials plays a major role in symbolic computation. Modular methods provide efficient approaches, of which Collins' algorithm is one of the best known. This paper presents an implementation of an algorithm based on linear recurring sequences for computing the resultant of two polynomials over a unique factorization domain. This method computes the resultant by means of a recursive function over a finite sequence with 2n - 1 elements, where n is the maximum degree of the given polynomials. Computing-time analysis shows that the modular version of this approach and Collins' algorithm for computing resultants have the same complexity. The implementation of this algorithm is given in Maple.
