用二聚体动力学计算主A-行列式

Computation of Principal A-determinants through Dimer Dynamics

Jan Stienstra

摘要:

本文将Gulotta的高效逆算法(arXiv:0807.3012)的图形化描述转化为矩阵运算,使之能在计算机上实现。作为一个应用程序,我们指出,这与我们的论文arXiv:0803.3908的结果相结合,提供了一个快速算法计算的主要A-行列式Gelfand,Kapranov和Zelevinsky的超几何系统在两个变量。

英文摘要:

In this note we translate the pictorial description of Gulotta's efficient inverse algorithm (arXiv:0807.3012) into matrix operations, so that it can be implemented on a computer. As an application we point out that this in combination with results from our paper arXiv:0803.3908 provides a fast algorithm for computing the principal A-determinant of Gelfand, Kapranov and Zelevinsky for hypergeometric systems in two variables.
