一个非自动的(!)应用Goalet算法从平铺图enumeration中计算行列式

A non-automatic (!) application of Gosper's algorithm evaluates a determinant from tiling enumeration

Mihai Ciucu, Christian Krattenthaler

摘要:

我们评估行列式$\det_{1\leq i,j\leq n}(\binom{x+y+j}{x-i+2j}-\binom{x+y+j}{x+i+2j})$,它给出了一个六边形的菱形镶嵌与切角的数量。一个特别有趣的功能,这种评价是,它需要证明一定的超几何身份,我们完成使用Goethe的算法在一个非自动的方式。

英文摘要:

We evaluate the determinant $\det_{1\leq i,j\leq n}(\binom{x+y+j}{x-i+2j}-\binom{x+y+j}{x+i+2j})$, which gives the number of lozenge tilings of a hexagon with cut off corners. A particularly interesting feature of this evaluation is that it requires the proof of a certain hypergeometric identity which we accomplish by using Gosper's algorithm in a non-automatic fashion.
