Graph theory distance
WebA distance vertex irregular total k-labeling of a simple undirected graph G = G(V, E), is a function f : V(G)∪E(G)→{1, 2, …, k} such that for every pair vertices u, v ∈ V(G) and u ≠ v, the weights of u and v are distinct.The weight of vertex v ∈ V(G) is defined to be the sum of the label of vertices in neighborhood of v and the label of all incident edges to v. WebAbstract The positive part U q + of U q ( sl ˆ 2 ) has a presentation with two generators W 0, W 1 and two relations called the q-Serre relations. The algebra U q + contains some elements, said to ...

WebDistance matrix. In mathematics, computer science and especially graph theory, a distance matrix is a square matrix (two-dimensional array) containing the distances, taken pairwise, between the elements of a set.
