Abstrak
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 polynomial of $G^σ$ are interpreted in terms of the graph structure of $G^σ$, and it is proved that all orientations $G^σ$ of $G$ have the same permanental polynomial if and only if $G$ has no even cycles. Furthermore, the roots of the permanental polynomial of $G^σ$ are studied.
