Studying Non-negative Factorizations with Tools from Linear Algebra over a Semiring
Yaroslav Nikolaevich Shitov · Communications in Algebra · 2015
We develop the technique useful for studying the problem of factoring nonnegative matrices. We illustrate our method, based on the tools from linear algebra over a semiring, by applying it to studying the problem of existence of a rank-three matrix with full nonnegative rank equal to n.
