Abelian sandpile model and Biggs-Merino polynomial for directed graphs
Swee Hong Chan
We prove several results concerning a polynomial that arises from the sandpile model on directed graphs; these results are previously only known for undirected graphs. Implicit in…

Quasi-periodic tiling with multiplicity: a lattice enumeration approach
Swee Hong Chan
The -tiling problem for a convex polytope is the problem of covering with translates of using a discrete multiset of translation vectors, such that eve…

Sandpile groups of generalized de Bruijn and Kautz graphs and circulant matrices over finite fields
Swee Hong Chan, Henk D. L. Hollmann, Dmitrii V. Pasechnik
A maximal minor of the Laplacian of an -vertex Eulerian digraph gives rise to a finite group known as the sandpile (or critical) gro…
