On the differentiability of functions in R n extbf {R}^{n} Academic Article uri icon


  • 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 GLn 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 Sn, the Weyl group of GLn. © 1984 American Mathematical Society.
