| Abstract: |
|---|
| I will discuss a Poisson structure on the flag
variety of a complex semisimple Lie group with the
property that its symplectic leaves are Richardson
varieties, i.e., intersections between Schubert cells
and opposite Schubert cells. This structure arises
by taking a certain limit of the Bruhat-Poisson structure
under a complex torus action. This talk is based on joint
work with Arlo Caine. |
