An edgeless graph is occasionally referred to as a null graph in contexts where the order-zero graph is not permitted. [1] [2] It is a 0-regular graph. The notation K n arises from the fact that the n-vertex edgeless graph is the complement of the complete graph K n.
A forest is an undirected acyclic graph or equivalently a disjoint union of trees. Trivially so, each connected component of a forest is a tree. As special cases, the order-zero graph (a forest consisting of zero trees), a single tree, and an edgeless graph, are examples of forests.

The graph of the Dirac delta is usually thought of as following the whole x-axis and the positive y-axis. [5]: ... Thus δ is a distribution of order zero.
In graph theory, a regular graph is a graph where each vertex has the same number of neighbors; i.e. every vertex has the same degree or valency. A regular directed graph must also satisfy the stronger condition that the indegree and outdegree of each internal vertex are equal to each other. [1]

A type of logic of graphs; see first order and second order. 3. An order or ordering of a graph is an arrangement of its vertices into a sequence, especially in the context of topological ordering (an order of a directed acyclic graph in which every edge goes from an earlier vertex to a later vertex in the order) and degeneracy ordering (an ...
