Let $\mathcal{G}_{n}^{c}$ be the set of all connected graphs on $n$ vertices, and let $G\in\mathcal{G}_{n}^{c}$ with $|V|=pq$. Star graph maximizer conjecture. … This asserts that…

Let $G$ be a graph with $|V|=pq$ and $m$ edges. For each edge, let $\sigma(k)$ denote the pure density matrix associated with the $k$-th edge. If $\sigma(G)$ is entangled in…

Let $\sigma$ be a state on a quadripartite Hilbert space … For each reduced state, take the entanglement of formation $E_F$ with respect to the corresponding bipartite A-B division…
