B型和C型各向同性Grassmannian的最小量子度

Minimum Quantum Degrees for Isotropic Grassmannians in Types B and C

Ryan M. Shifler, Camron Withrow

摘要:

对于B型和C型的次极大各向同性格拉斯曼算子,给出了一个利用Young图计算最小正整数$d$的公式,使得$q^d$出现在两个Schubert类的量子积中.我们通过研究曲线邻域来做到这一点。我们计算曲线邻域在几个组合模型,包括$k$严格分区和一组分区,其中它们的列入是兼容的Bruhat顺序。

英文摘要:

We give a formula in terms of Young diagrams to calculate the minimum positive integer $d$ such that $q^d$ appears in the quantum product of two Schubert classes for the submaximal isotropic Grassmannians in Types B and C. We do this by studying curve neighborhoods. We compute curve neighborhoods in several combinatorial models including $k$-strict partitions and a set of partitions where their inclusion is compatible with the Bruhat order.
