Graph strong product
Did you know?
In graph theory, the strong product is a way of combining two graphs to make a larger graph. Two vertices are adjacent in the strong product when they come from pairs of vertices in the factor graphs that are either adjacent or identical. The strong product is one of several different graph product operations that have been studied in graph theory. The strong product of any two graphs can be constructed as the union of two other products of the same two graphs, the Cartesian pr… WebApr 19, 2024 · in general. Then we can define the Kronecker product entry-by-entry as. ( A × B) ( i 1, i 2), ( j 1, j 2) = A i 1, j 1 B i 2, j 2. By itself, the Kronecker product would give …
WebJul 1, 2008 · Cartesian product. 1. Introduction. The connectivity of a simple graph G = ( V ( G), E ( G)) is the number, denoted as κ ( G), equal to the fewest number of vertices whose removal from G results in a disconnected or trivial graph. The Cartesian product of graphs G and H is the graph G H with vertices V ( G H) = V ( G) × V ( H), and for which ... WebAug 9, 2024 · Graph product plays a key role in many applications of graph theory because many large graphs can be constructed from small graphs by using graph products.

WebThe Wiener index of a connected graph \(G\) is the sum of distances between all pairs of vertices of \(G\). The strong product is one of the four most investigated graph products. In this paper the general formula for the Wiener index of the strong product of connected graphs is given.

WebThis note shows that for two connected graphs G1 and G2 the edge-connectivity λ(G1£G2) equals min, and fully describes the structure of possible minimum edge cut sets in strong products of graphs. The strong product G1 £G2 of graphs G1 and G2 is the graph with V (G1) × V (G2) as the vertex set, and two distinct vertices (x1, x2) and (y1, y2) are …
In graph theory, a graph product is a binary operation on graphs. Specifically, it is an operation that takes two graphs G1 and G2 and produces a graph H with the following properties: • The vertex set of H is the Cartesian product V(G1) × V(G2), where V(G1) and V(G2) are the vertex sets of G1 and G2, respectively. • Two vertices (a1,a2) and (b1,b2) of H are connected by an edge, iff a condition about a1, b1 in G1 and a2, b2 in G2 is fulfilled. great deals on laptops for studentsNov 16, 2016 · great deals on kitchen appliancesWebMar 24, 2024 · The graph strong product, also known as the graph AND product or graph normal product, is a graph product variously denoted , (Alon, and Lubetzky 2006), or (Beineke and Wilson 2004, p. 104) defined by the adjacency relations (and ) or (and ) … The vertex set of a graph is simply a set of all vertices of the graph.
