AI总结:

本文提出一种简单算法,用于计算纯五次域中的幂积分基生成器,通过改进的筛法显著减少需考虑的小指数数量。

摘要:

我们提供了一种简单算法,用于计算纯五次域中所有幂积分基的生成器。该过程涉及通常的标准元素,如Baker的方法和LLL约简。本文的主要目的是引入一种新思想,显著减少约简步骤后需考虑的小指数数量。这种新思想允许在几分钟内测试所有剩余的小指数,使用适当筛法,结果出人意料地快速。该思想将在许多类似情况下适用。

英文摘要:

We provide a simple algorithm for calculating all generators of power integral bases in pure quintic fields. This procedure involves the usual standard elements like Baker's method, LLL-reduction. The main purpose of the paper is to introduce a new idea to considerably diminish the number of small exponents to be considered after the reduction step. This new idea allows to test all remaining small exponents within a few minutes, using an appropriate sieve method, which turns out to be surprisingly fast. This idea will be applicable in many similar cases.
