Richard Ellard, Helena Šmigoc

We say that a list of real numbers is "symmetrically realisable" if it is the spectrum of some (entrywise) nonnegative symmetric matrix. The Symmetric Nonnegative Inverse Eigenvalu…

The effect of assuming the identity as a generator on the length of the matrix algebra

Thomas Laffey, Olga Markova, Helena Šmigoc

Let $M_{n} (F)$ be the algebra of $n \times n$ matrices and let $S$ be a generating set of $M_{n} (F)$ as an $F$ -algebra. The length of a finite gener…
