White's Conjecture for Paving Matroids
Yu-Chuan Yu, Chi Ho Yuen
White's conjecture asserts that any two tuples of matroid bases that have the same multi-set union can be transformed from one to another by symmetric exchanges; it also implies th…
Period matrices and homological quasi-trees on discrete Riemann surfaces
Wai Yeung Lam, On-Hei Solomon Lo, Chi Ho Yuen
We study discrete period matrices associated with graphs cellularly embedded on closed surfaces, resembling classical period matrices of Riemann surfaces. Defined via integrals of…
Filtrations of Tope Spaces of Oriented Matroids
Kris Shaw, Chi Ho Yuen
We compare three filtrations of the tope space of an oriented matroid. The first is the dual Varchenko-Gelfand degree filtration, the second filtration is from Kalinin's spectral s…
A Consistent Sandpile Torsor Algorithm for Regular Matroids
Changxin Ding, Alex McDonough, Lilla Tóthmérész +1
Every regular matroid is associated with a sandpile group, which acts simply transitively on the set of bases in various ways. Ganguly and the second author introduced the notion o…
The amoeba dimension of a linear space
Jan Draisma, Sarah Eggleston, Rudi Pendavingh +2
Given a complex vector subspace of , the dimension of the amoeba of depends only on the matroid that defines on the ground set $\{1,…
The Critical Groups of Adinkras up to 2-Rank of Cayley Graphs
Chi Ho Yuen
Adinkras are graphical gadgets introduced by physicists to study supersymmetry, which can be thought of as the Cayley graphs for supersymmetry algebras. Improving the result of Iga…
