Enumeration of copermanental graphs

Shunyi Liu, Jinjun Ren

Let $G$ be a graph and $A$ the adjacency matrix of $G$ . The permanental polynomial of $G$ is defined as $per (x I - A)$ . In this paper some of the results from a numerical stu…

Permanental polynomials of skew adjacency matrices of oriented graphs

Shunyi Liu, Heping Zhang

Let $G^{σ}$ be an orientation of a simple graph $G$ . In this paper, the permanental polynomial of an oriented graph $G^{σ}$ is introduced. The coefficients of the permanental polynomia…
