Alternating Sign Matrices and Hypermatrices, and a Generalization of Latin Square
Richard A. Brualdi,Geir Dahl +1 more
TL;DR: This work investigates completion problems, in which one asks if a subhypermatrix can be completed (extended) into an ASHM, and shows several theorems of this type of hypermatrix.
Journal ArticleDOI
On the poset of all posets on n elements
TL;DR: This work considers the poset of all posets on n elements where the partial order is that of inclusion of comparabilities and discusses some properties of this poset concerning its height, width, jump number and dimension.
A combinatorial proof of the dodgson/muir determinantal identity
TL;DR: In this article, the Dodgson/Muir identity has been generalized to an identity called DodGson-Muir Identity (DMI) by using Muir's law of extensible minors.
