$A$ -超几何系统的特征环与Gevrey级数解

Characteristic cycles and Gevrey series solutions of $A$-hypergeometric systems

Christine Berkesch, María-Cruz Fernández-Fernández

摘要:

我们计算了$A$ -超几何系统的$L$ -特征环和复曲面环的高阶Euler-Koszul同调模.我们还证明了这些循环中重数的上连续性结果,并应用我们的结果分析了系统的Gevrey解空间的行为。

英文摘要:

We compute the $L$-characteristic cycle of an $A$-hypergeometric system and higher Euler-Koszul homology modules of the toric ring. We also prove upper semicontinuity results about the multiplicities in these cycles and apply our results to analyze the behavior of Gevrey solution spaces of the system.
