Graph theory block
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 have the same length, a weakening of the characterization of block graphs as having at … 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 WebA signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, but often called a Mason graph after Samuel Jefferson Mason who coined the term, is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes. Thus, …

A graph G = ( V, E) that is not simple can be represented by using multisets: a loop is a multiset { v, v } = { 2 ⋅ v } and multiple edges are represented by making E a multiset. The condensation of a multigraph may be formed by interpreting the multiset E as a set. A general graph that is not connected, has ...
