Shape and pattern containment of separable permutations
Andrew Crites, Greta Panova, Gregory S. Warrington
Every word has a shape determined by its image under the Robinson-Schensted-Knuth correspondence. We show that when a word w contains a separable (i.e., 3142- and 2413-avoiding) pe…

Pattern characterization of rationally smooth affine Schubert varieties of type A
Sara Billey, Andrew Crites
Schubert varieties in finite dimensional flag manifolds G/P are a well-studied family of projective varieties indexed by elements of the corresponding Weyl group W. In particular,…

Enumerating pattern avoidance for affine permutations
Andrew Crites
In this paper we study pattern avoidance for affine permutations. In particular, we show that for a given pattern p, there are only finitely many affine permutations in $\widetilde…
