WebGraph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges. (In the figure below, the vertices are the numbered circles, and the edges join the vertices.) A … Web4.2 A characterization for 2-connectedness 4.2.2 Theorem. (Whitney [1932]) A graph G having at least 3 vertices is 2-connected iff for all u,v ∈ V(G) there exist internally disjoint u,v-paths in G. Induction step d(u,v) > 1 Let w be the vertex adjacent to v on some shortest u,v-path. Since d(u,w)=d(u,v)–1, by induction there exist internally disjoint sojourn chattanooga https://gonzojedi.com

In an undirected graph G, two vertices u and v are called connected if G contains a path from u to v. Otherwise, they are called disconnected. If the two vertices are additionally connected by a path of length 1, i.e. by a single edge, the vertices are called adjacent. A graph is said to be connected if every pair of … See more In mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to separate the remaining nodes … See more A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected component, as does each edge. A graph is connected if and only if it has exactly one connected component. The See more The problem of determining whether two vertices in a graph are connected can be solved efficiently using a search algorithm, such as See more • The vertex-connectivity of a graph is less than or equal to its edge-connectivity. That is, κ(G) ≤ λ(G). Both are less than or equal to the minimum degree of the graph, since deleting all neighbors of a vertex of minimum degree will disconnect that vertex from the rest … See more One of the most important facts about connectivity in graphs is Menger's theorem, which characterizes the connectivity and edge-connectivity of a graph in terms of the number of independent paths between vertices. If u and v are … See more • The vertex- and edge-connectivities of a disconnected graph are both 0. • 1-connectedness is equivalent to connectedness for … See more • Connectedness is preserved by graph homomorphisms. • If G is connected then its line graph L(G) is also connected.

WebAlmost all graph theory books and articles define a spanning forest as a forest that spans all of the vertices, meaning only that each vertex of the graph is a vertex in the forest. A connected graph may have a disconnected spanning forest, such as the forest with no edges, in which each vertex forms a single-vertex tree. A few graph theory ... WebIn the mathematical theory of directed graphs, a graph is said to be strongly connected if every vertex is reachable from every other vertex. The strongly connected components of an arbitrary directed graph form a partition into subgraphs that are themselves strongly connected.
