Power-universality support conjecture. Under these support conditions, $(\rho,\sigma)$ is power universal in the semiring. The claim is part of a sufficient, though not expected to…

Let $S_{\rm res}^d$ be a semiring of matrices with support restrictions, and let $U$ be a matrix whose columns all sum to one. A matrix $U$ is power universal if it satisfies the r…
