A tree of a graph is a connected subgraph that contains all nodes of the graph and it has no loop. Tree is very important for loop and curset analyses. A Tree of a graph is generally not unqiue. Branches that are not in the tree are called links.

WebJan 27, 2024 · Suppose for a contradiction that given graph exists. Then since one vertex out of eight has degree $7$, this vertex is connected all other vertices. Now, consider the vertex with degree $5$, which has one edge connected to the vertex with degree $7$. In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a vertex's degree, for the two ends of the edge. The degree of a vertex is denoted or . The maximum degree of a graph , denoted by , and the minimum degree of a graph, denoted by , are the maximum and minimum of its vertices' degrees. In …
