Cage (graph theory) - Wikipedia
Known cages A degree-one graph has no cycle, and a connected degree-two graph has girth equal to its number of vertices, so cages are only of interest for r ? 3. The ( r ,3)-cage is a complete graph K

Dominating set - Wikipedia
Dominating sets are closely related to independent sets : a maximal independent set in a graph is necessarily a minimal dominating set. However, dominating sets need not be independent, and there has been much work on connected dominating sets .

Line graph - Wikipedia
Many of the following properties follow immediately from the standard way in which line graphs translate properties about edges in graphs to properties about vertices. The line graph of a connected graph is connected. The line graph of a bipartite graph is perfect (see König's theorem ). The edge chromatic number of a graph

Path (graph theory) - Wikipedia
In graph theory , a path in a graph is a sequence of vertices such that from each of its vertices there is an edge to the next vertex in the sequence. The first vertex is called the start vertex and the last vertex is called the end vertex . Both of them are called end or terminal vertices of the path. The other vertices in the path

Dense graph - Wikipedia
The opposite, a graph with only a few edges, is a sparse graph . The distinction between sparse and dense graphs is rather vague. One possibility is to choose a number k with 1 < k < 2 and to define sparse graph
