超几何创造性伸缩的阶次曲线

Order-Degree Curves for Hypergeometric Creative Telescoping

Shaoshi Chen, Manuel Kauers

摘要:

创造性的伸缩适用于一个二元适当的超几何项产生的线性递归算子多项式系数,称为递归算子。我们提供的界限出现在这些运营商的多项式的程度。我们的界限表示为(r,d)平面中的曲线,该曲线为每个阶r分配了望远镜度数d的界限。这些曲线都是双曲线,反映了高阶复指数越低,反之亦然的现象。

英文摘要:

Creative telescoping applied to a bivariate proper hypergeometric term produces linear recurrence operators with polynomial coefficients, called telescopers. We provide bounds for the degrees of the polynomials appearing in these operators. Our bounds are expressed as curves in the (r,d)-plane which assign to every order r a bound on the degree d of the telescopers. These curves are hyperbolas, which reflect the phenomenon that higher order telescopers tend to have lower degree, and vice versa.
