受 Di Francesco 的二十顶点构型行列式启发的行列式求值

Determinant evaluations inspired by Di Francesco's determinant for twenty-vertex configurations

Christoph Koutschan, Christian Krattenthaler, Michael Schlosser

AI总结:

本文证明了 Di Francesco 关于二十顶点模型构型数量行列式求值的闭式乘积公式猜想,将其推广至单参数族,并给出了更多类似类型的行列式求值。

摘要:

在其关于二十顶点模型的工作中,Di Francesco [Electron. J. Combin. 28(4) (2021), Paper No. 4.38] 找到了一个特定此类模型中构型数量的行列式公式,并猜想了一个用于该行列式求值的闭式乘积公式。我们在此证明了这一猜想。此外,我们实际上将该行列式求值推广到了一个单参数族的行列式求值,并且给出了更多类似类型的行列式求值——一些已被证明,一些作为猜想留待解决。

英文摘要:

In his work on the twenty vertex model, Di Francesco [Electron. J. Combin. 28(4) (2021), Paper No. 4.38] found a determinant formula for the number of configurations in a specific such model, and he conjectured a closed form product formula for the evaluation of this determinant. We prove this conjecture here. Moreover, we actually generalize this determinant evaluation to a one-parameter family of determinant evaluations, and we present many more determinant evaluations of similar type - some proved, some left open as conjectures.
