For a prime , the OM algorithm finds the -adic factorization of an irreducible polynomial in polynomial time. This may be applied to construct -integral bases in the number field defined by . In this paper, we adapt the OM techniques to work with a positive integer instead of . As an application, we obtain an algorithm to compute global integral bases in , which does not require a previous factorization of the discriminant of .

全局积分基的无平方 OM 计算
对于一个素数, OM 算法找到-不可约多项式的进数因式分解在多项式时间内。这可以应用于构建- 数字字段中的整数碱基被定义为. 在本文中,我们采用 OM 技术来处理正整数代替. 作为一个应用程序,我们获得了一种计算全局积分基的算法,这不需要事先对 的判别式进行因式分解.
