The edge covering of $G$ is a set of edges such that every vertex of $G$ is incident to at least one edge of the set. The edge cover polynomial of $G$ is the polynomial$E(G,x)=sum_{i=rho(G)}^{m} e(G,i) x^{i}$, where $e(G,i)$ is the number of edge coverings of $G$ of size $i$, and$rho(G)$ is the edge covering number of $G$. In this paper we study the edge cover polynomials of cubic graphs of order $10$. We show that all cubic graphs of order $10$ (especially the Petersen graph) are determined uniquely by their edge cover polynomials.}, keywords = {Edge cover polynomial,edge covering,equivalence class,cubic graph,corona}, url = {https://jas.shahroodut.ac.ir/article_359.html}, eprint = {https://jas.shahroodut.ac.ir/article_359_03bd853b0f975a60d986af404d928abd.pdf} }
