Bn型仿射Weyl群a值5的A2×A12×A11型左胞腔

Left Cells of A2×A12×A11 with a-value 5 in Affine Weyl Group of Type Bn

    摘要
  • 摘要: 描述了Bn型仿射Weyl群a值为5的A2×A12×A11型左胞腔的个数.通过计算得到：当n=7时，这样的左胞腔个数为32；当n ≥ 8时，左胞腔个数为1/（12）（n4-2n3-55n2+224n-204）.

     

    Abstract: The number of left cells of A2×A12×A11 in type Bn affine Weyl group with a value of 5 was described and calculated. It was obtained that the number of such left cells is 32 for n=7; 1/(12)(n4-2n3-55n2+224n-204) for n ≥ 8.
