Definition:Vertex Set

Definition
Let $G = \left({V, E}\right)$ be a graph.

The set $V$ of vertices in $G$ is called the vertex set.

It is often convenient to refer to the vertex set for a given graph $G$ as $V \left({G}\right)$, especially if there is at any one time more than one graph under consideration.
