On intersections of orbital varieties and components of Springer fiber

Research output: Contribution to journalArticlepeer-review


We consider Springer fibers and orbital varieties for GLn. We show that the irreducible components of an intersection of components of Springer fiber are in bijection with the irreducible components of intersection of orbital varieties; moreover, the corresponding irreducible components in this correspondence have the same codimension. Finally we give a sufficient condition to have an intersection in codimension one.
