Positive Square Energy of Graphs with Minimum Degree at Least Two

S. Akbari, Fu-Tao Hu, Ya-Yang Liu

Let $s^{+} (G)$ denote the sum of the squares of the positive adjacency eigenvalues of a graph $G$ . The square-energy conjecture of Elphick, Farber, Goldberg, and Wocjan, proved by Li…

Positive and Negative Square Energies of $2$ -Connected Graphs

S. Akbari, Fu-Tao Hu, Ya-Yang Liu

Let $G$ be a graph of order $n$ , and let $s^{+} (G)$ and $s^{-} (G)$ denote the sums of the squares of the positive and negative adjacency eigenvalues of $G$ , respectively. Recently, Liu…

On Prime Matrix Product Factorizations

Saieed Akbari, Mohamad Parsa Elahimanes, Bobby Miraftab

A graph $G$ factors into graphs $H$ and $K$ via a matrix product if $A = B C$ , where $A$ , $B$ , and $C$ are the adjacency matrices of $G$ , $H$ , and $K$ , respectively. The graph $G$ i…

Spectral Methods for Matrix Product Factorization

Saieed Akbari, Yi-Zheng Fan, Fu-Tao Hu +2

A graph $G$ is factored into graphs $H$ and $K$ via a matrix product if there exist adjacency matrices $A$ , $B$ , and $C$ of $G$ , $H$ , and $K$ , respectively, such that $A = B C$ . In…
