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…
Matrices with restricted entries and q-analogues of permutations
Joel Brewster Lewis, Ricky Ini Liu, Alejandro H. Morales +3
We study the functions that count matrices of given rank over a finite field with specified positions equal to zero. We show that these matrices are -analogues of permutations w…
Tableaux and plane partitions of truncated shapes
Greta Panova
We consider a new kind of straight and shifted plane partitions/Young tableaux --- ones whose diagrams are no longer of partition shape, but rather Young diagrams with boxes erased…
Factorization of banded permutations
Greta Panova
We consider the factorization of permutations into bandwidth 1 permutations, which are products of mutually nonadjacent simple transpositions. We exhibit an upper bound on the mini…
