Bootstrap Percolation, Indecomposable Permutations, and the n-Kings problem

Mark Huibregtse, Cristobal Lemus-Vidales, David Vella

We study the process of bootstrap percolation on n x n permutation matrices, inspired by the work of Shapiro and Stephens [5]. In this percolation model, cells mutate (from 0 to 1)…

Nilpotent Orbits for Borel Subgroups of $S O_{5} (k)$

Madeleine Burkhart, David Vella

Let $G$ be a quasi-simple algebraic group defined over an algebraically closed field $k$ and $B$ a Borel subgroup of $G$ acting on the nilradical $n$ of its Lie algebra…

Primary Decomposition in Boolean Rings

David C. Vella

Students studying the Lasker-Noether theorem on primary decomposition of ideals may want to see an example of an ideal (necessarily in a non-Noetherian ring) which does not have a…
