关于阶乘比和镜像映射的完整性

On the integrality of factorial ratios and mirror maps

Alan Adolphson, Steven Sperber

摘要:

朗道已经刻画了某些因子比率的完整性。Delaygue刻画了由包含这些比率的级数所构造的某些镜像映射的泰勒系数的完整性。使用$A$ -超几何的观点,我们表示的内点的不存在性的相关的格多面体的倍数方面的这些特征。

英文摘要:

Landau has characterized the integrality of certain ratios of factorials. Delaygue has characterized the integrality of the Taylor coefficients of certain mirror maps constructed from series involving those ratios. Using the $A$-hypergeometric point of view, we express those characterizations in terms of the nonexistence of interior points in multiples of the associated lattice polytope.
