Graph theory vertex
WebMar 24, 2024 · A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with n graph vertices is denoted K_n and has (n; 2)=n(n-1)/2 (the triangular numbers) undirected edges, where (n; k) is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs. … WebMar 24, 2024 · A subset of that meets every member of is called the vertex cover, or hitting set.

WebIn graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, ... More generally, a vertex in a graph that belongs to three shortest paths among three vertices is called a median of these vertices. Because every three vertices in a tree have a unique median, every tree is a median graph. WebThe vertex corresponding to the deleted row in Af is called the reference vertex. Clearly, any vertex of a connected graph can be made the reference vertex. Since a tree is a connected graph with n vertices and n − 1 edges, its reduced incidence matrix is a square matrix of order and rank n − 1.
In discrete mathematics, and more specifically in graph theory, a vertex (plural vertices) or node is the fundamental unit of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges (unordered pairs of vertices), while a directed graph consists of a set of vertices and a … See more The degree of a vertex, denoted 𝛿(v) in a graph is the number of edges incident to it. An isolated vertex is a vertex with degree zero; that is, a vertex that is not an endpoint of any edge (the example image illustrates one … See more • Node (computer science) • Graph theory • Glossary of graph theory See more • Weisstein, Eric W. "Graph Vertex". MathWorld. See more WebDefinition: A subgraph of a graph is a graph whose vertex and edge sets are subsets of the vertex and edge sets of G, respectively. A spanning subgraph is one that has the same vertex set as G(i.e., uses all of the vertices of G). Definition: A weighted graph is a graph that has a number assigned to each edge.
