Schubert胞腔Chern类的Pieri和Murnaghan-Nakayama型定则

Pieri and Murnaghan--Nakayama type Rules for Chern classes of Schubert Cells

Neil J. Y. Fan, Peter L. Guo, Rui Xiong

摘要:

我们发展Pieri型以及Murnaghan-Nakayama型公式的等变Chern-Schwartz-MacPherson类Schubert细胞的经典旗品种。这些公式包括作为特殊情况下,许多以前已知的乘法公式陈-施瓦茨-麦克弗森类或舒伯特类。我们应用等变的Murnaghan-Nakayama公式来计数边缘钩tableaux。

英文摘要:

We develop Pieri type as well as Murnaghan--Nakayama type formulas for equivariant Chern--Schwartz--MacPherson classes of Schubert cells in the classical flag variety. These formulas include as special cases many previously known multiplication formulas for Chern--Schwartz--MacPherson classes or Schubert classes. We apply the equivariant Murnaghan--Nakayama formula to the enumeration of rim hook tableaux.
