## Summary

In graph theory, the **bipartite double cover** of an undirected graph $G$ is a [[bipartite|07DVHJ8N0A]], covering graph of $G$, with twice as many vertices as $G$. It can be constructed as the tensor product of graphs, $G \times K_{2}$. It is also called the **Kronecker double cover**, **canonical double cover** or simply the **bipartite double** of $G$.
