A generalization of Eulerian numbers via rook placements
Esther Banaian, Steve Butler, Christopher Cox +3
We consider a generalization of Eulerian numbers which count the number of placements of "rooks" on an board where there are exactly rooks in each row and each…

Successful Pressing Sequences for a Bicolored Graph and Binary Matrices
Joshua Cooper, Jeffrey Davis
We apply matrix theory over to understand the nature of so-called "successful pressing sequences" of black-and-white vertex-colored graphs. These sequences arise in…
