SPN graphs: when copositive=SPN

Naomi Shaked-Monderer

A real symmetric matrix $A$ is copositive if $x^{T} A x \geq 0$ for every nonnegative vector $x$ . A matrix is SPN if it is a sum of a real positive semidefinite matrix and a nonnegative…

On the DJL conjecture for order 6

Naomi Shaked-Monderer

In 1994 Drew, Johnson and Loewy conjectured that for $n \geq 4$ , the cp-rank of any $n \times n$ completely positive matrices is at most $⌊ n^{2} / 4 ⌋$ . Recently this conj…

New results on the cp rank and related properties of co(mpletely)positive matrices

Naomi Shaked-Monderer, Abraham Berman, Immanuel M. Bomze +2

Copositive and completely positive matrices play an increasingly important role in Applied Mathematics, namely as a key concept for approximating NP-hard optimization problems. The…
