Abstract:
Combinatorial results are used to calculate the dimension of the intersection of any two irreducible components of the set in the flag variety fixed by the action of a unipotent element of ${\text {G}}{{\text {L}}_n}$ whose Jordan decomposition has two blocks. This is then related to the "left cells" of Kazhdan and Lusztig, which are used to construct representations of ${S_n}$, the Weyl group of ${\text {G}}{{\text {L}}_n}$.References
