A metric space defined over a set of points in terms of distances in a graph defined over the set is called a graph metric. The vertex set (of an undirected graph) and the distance function form a metric space, if and only if the graph is connected. The eccentricity ϵ(v) of a vertex v is the greatest distance between v and any other vertex; in symbols, WebMar 24, 2024 · A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with n graph vertices is denoted K_n and has (n; 2)=n(n-1)/2 (the triangular numbers) undirected edges, where (n; k) is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs. …

WebMar 20, 2024 · We obtain a relationship between the Laplacian energy and the distance Laplacian energy for graphs with diameter 2. We obtain lower bounds for the distance Laplacian energy DLE ( G) in terms of the order n, the Wiener index W ( G ), the independence number, the vertex connectivity number and other given parameters. WebDec 4, 2002 · For a power law random graph with exponent β > 3 and average degree d strictly greater than1, almost surely the average distance is (1 + o(1))(log n/logd̃) and the diameter is Θ(log n).

WebSep 27, 2024 · The diameter of the cycle C m is given by. diam ( C m) = { m 2 if m is even m − 1 2 if m is odd. I tried to show this using induction, since it's true for the base cases n = 2 and n = 3 . Now, if I assume that it is true for some m ∈ N - let's first assume that m is odd. Then the largest distance is m − 1 2.
