关系理想与Buchberger-Möller算法
Relation ideals and the Buchberger--Möller algorithm
摘要:
构造了多项式关系理想的Gröbner基,给出了基元的插值公式,并说明了该插值公式与Buchberger-Möller算法的联系.我们提出了一种情况下,使用的Buchberger-Möller算法是过时的,因为人们可以直接计算其结果。我们证明了伽罗瓦定理的一个建设性的版本,关于合理多项式的素数次数的可解性。计算进行了一些示例多项式。
英文摘要:
We construct a Gröbner Basis of the relation ideal of a polynomial, give an interpolation formula for the basis elements and explain the connection of the interpolation formula to the Buchberger--Möller algorithm. We present a situation in which the usage of the Buchberger--Möller algorithm is obsolete since one can compute its result directly. We prove a constructive version of a theorem of Galois, concerning the solvability of rational polynomials of prime degree. Computations are carried out for a number of example polynomials.
