The combinatorics of pattern-avoiding matrices

open access: yes, 2023
A permutation matrix P partially avoids a quasi-permutation matrix A (i.e., a 01- matrix such that each column and row of A contains at most one nonzero entry) if there is no submatrix P′ of P of the same size as A satisfying Ai,j ≤ P′ i,j for all ...

Generating functions for Wilf equivalence under generalized factor order

open access: yes, 2010
Kitaev, Liese, Remmel, and Sagan recently defined generalized factor order on words comprised of letters from a partially ordered set $(P, \leq_P)$ by setting $u \leq_P w$ if there is a subword $v$ of $w$ of the same length as $u$ such that the $i$-th character of $v$ is greater than or equal to the $i$-th character of $u$ for all $i$. This subword $v$
