Proper permutations, Schubert geometry, and randomness

David Brewster, Reuven Hodges, Alexander Yong

英文摘要:

We define and study proper permutations. Properness is a geometrically natural necessary criterion for a Schubert variety to be Levi-spherical. We prove the probability that a random permutation is proper goes to zero in the limit.
