Alternating sign matrices of finite multiplicative order

Cian O'Brien, Rachel Quinlan

We investigate alternating sign matrices that are not permutation matrices, but have finite order in a general linear group. We classify all such examples of the form $P + T$ , where…

Linear diophantine equations in several variables

Rachel Quinlan, Moumita Shau, Fernando Szechtman

Let $R$ be a ring and let $(a_{1}, \dots, a_{n}) \in R^{n}$ be a unimodular vector, where $n \geq 2$ and each $a_{i}$ is in the center of $R$ . Consider the linear equation $a_1X_1+\cdots+a_nX_…
