我们提出了一种高阶算术牛顿多边形理论,它提供了p进域上可分离多项式的分解,以及由不可约因子生成的域的相关算术信息。这执行了由。作为一个应用,我们获得了数域的判别、素数理想分解和积分基的快速计算算法。
We develop a theory of arithmetic Newton polygons of higher order, that provides the factorization of a separable polynomial over a p-adic eld, together with relevant arithmetic information about the elds generated by the irreducible factors. This carries out a program suggested by . Ore. As an application, we obtain fast algorithms to compute discriminants, prime ideal decomposition and integral bases of number elds.
