超几何创新望远镜的新界

New Bounds for Hypergeometric Creative Telescoping

Hui Huang

摘要:

基于Abramov-Petkovšek约化的一个改进版本,去年开发了一个计算二元超几何项的最小可达性的新算法。我们在本文中进一步研究并提出了终止该算法的新论据,它提供了远程探测器存在的独立证明,甚至使我们能够推导出超几何项的远程探测器阶数的下界和上界。与文献中已知的界相比,我们的界有时更好,但绝不会比已知的更差。

英文摘要:

Based on a modified version of Abramov-Petkovšek reduction, a new algorithm to compute minimal telescopers for bivariate hypergeometric terms was developed last year. We investigate further in this paper and present a new argument for the termination of this algorithm, which provides an independent proof of the existence of telescopers and even enables us to derive lower as well as upper bounds for the order of telescopers for hypergeometric terms. Compared to the known bounds in the literature, our bounds are sometimes better, and never worse than the known ones.
