symmetric structures in the strong bruhat order
abstract:
the bruhat order encodes algebraic and topological information of schubert varieties in the flag manifold and possesses rich combinatorial properties. in this talk, we discuss three interrelated stories regarding the bruhat order: self-dual bruhat intervals, billey-postnikov decompositions, and automorphisms of the bruhat graph. this is joint work with christian gaetz.
