Column convex matrices, -cyclic orders, and flow polytopes
Rafael S. González D'León, Christopher R. H. Hanusa, Alejandro H. Morales +1
We study polytopes defined by inequalities of the form for and nonnegative where the inequalities can be reordered into a matrix…
A billiards-like dynamical system for attacking chess pieces
Christopher R. H. Hanusa, Arvind V. Mahankali
We apply a one-dimensional discrete dynamical system originally considered by Arnol'd reminiscent of mathematical billiards to the study of two-move riders, a type of fairy chess p…
Lecture hall partitions and the affine hyperoctahedral group
Christopher R. H. Hanusa, Carla D. Savage
In 1997 Bousquet-Mélou and Eriksson introduced lecture hall partitions as the inversion vectors of elements of the parabolic quotient . We provide a new view of th…
Pseudo-centrosymmetric matrices, with applications to counting perfect matchings
Christopher R. H. Hanusa
We consider square matrices A that commute with a fixed square matrix K, both with entries in a field F not of characteristic 2. When K^2=I, Tao and Yasuda defined A to be generali…
A Gessel-Viennot-type method for cycle systems in a directed graph
Christopher R. H. Hanusa
We introduce a new determinantal method to count cycle systems in a directed graph that generalizes Gessel and Viennot's determinantal method on path systems. The method gives new…
