This category contains results about Euler Characteristic of Finite Graph.
Definitions specific to this category can be found in Definitions/Euler Characteristic of Finite Graph.
Let $G = \struct {V, E}$ be a finite graph.
Let $G$ be embedded in a surface.
The Euler characteristic of $G$ is written $\map \chi G$ and is defined as:
- $\map \chi G = v - e + f$
