WebJan 1, 2013 · The Kirchhoff index is the sum of resistance distances between all pairs of vertices in G. Zhou and Trinajstić (Chem Phys Lett 455(1–3):120–123, 2008) obtained a Nordhaus-Gaddum-type result ... WebMar 15, 2024 · Planarity: A graph is said to be planar if it can be drawn on a plane without any edges crossing each other. Bipartiteness: A graph is said to be bipartite if its vertices can be divided into two disjoint sets such that no two vertices in the same set are connected by an edge. Properties of Graphs are basically used for the characterization of ...
Webgraph and its complement are known as Nordhaus-Gaddum inequal-ities. In this paper, some variations on this result is studies. First, recall their theorem, which gives bounds on the sum and the product of the chromatic number of a graph with that of its complement. we also provide a new characterization of the certain graph classes. WebThe energy of the graph had its genesis in 1978. It is the sum of absolute values of its eigenvalues. It originates from the π -electron energy in the Huckel molecular orbital model but has also gained purely mathematical interest. ... T1 - Laplacian energy of partial complement of a graph.

Web(c)Find a simple graph with 5 vertices that is isomorphic to its own complement. (Start with: how many edges must it have?) Solution: Since there are 10 possible edges, Gmust have 5 edges. One example that will work is C 5: G= ˘=G = Exercise 31. (a)Draw the isomorphism classes of connected graphs on 4 vertices, and give the vertex and edge
WebDec 1, 1998 · Let G = (V,E) be a graph on n vertices. Denote by d(v) the degree of v ∈ V and by m(v) the average of the degrees of the vertices of G adjacent to v.Then b(G) = max{m(v) + d(v): v ∈ V} is an upper bound for the Laplacian spectral radius of G; hence, n − b(G C) is a lower bound for the algebraic connectivity of G in terms of the vertex degrees … chrysler culpeper vaWebWe know that for any graph G the independence number D(G) is always equal to the clique number of its complement Z(G), i.e., If Z(G) is the clique number of the graph G and D(G) is the independence number of its complement G the we have, Z(G) D(G).
