Block graph theory
In graph theory, a branch of combinatorial mathematics, a block graph or clique tree is a type of undirected graph in which every biconnected component (block) is a clique. Block graphs are sometimes erroneously called Husimi trees (after Kôdi Husimi), but that name more properly refers to cactus graphs, … See more Block graphs are exactly the graphs for which, for every four vertices u, v, x, and y, the largest two of the three distances d(u,v) + d(x,y), d(u,x) + d(v,y), and d(u,y) + d(v,x) are always equal. They also have a See more Block graphs are chordal, distance-hereditary, and geodetic. The distance-hereditary graphs are the graphs in which every two induced paths between the same two vertices … See more If G is any undirected graph, the block graph of G, denoted B(G), is the intersection graph of the blocks of G: B(G) has a vertex for every biconnected component of G, … See more WebMar 6, 2015 · In this video we look at two terms which are related to the idea of cut-vertices in a graph.

WebEvery edge of a graph belongs in exactly one block. 2. The block graph of a graph G is another graph whose vertices are the blocks of G, with an edge connecting two vertices when the corresponding blocks share an articulation point; that is, it is the intersection graph of the blocks of G. The block graph of any graph is a forest. 3. WebThe stochastic block model is a generative model for random graphs.This model tends to produce graphs containing communities, subsets of nodes characterized by being connected with one another with particular edge densities.For example, edges may be more common within communities than between communities. Its mathematical formulation …
WebThe block-cutpoint graph of a graph G is the bipartite graph which consists of the set of cut-vertices of G and a set of vertices which represent the blocks of G. Let G = ( V, E) be a connected graph. Let v be a vertex of G. Then v is a cut-vertex of G iff the vertex deletion G − v is a vertex cut of G .That is, such that G − v is disconnected.
