maximum degree

Let G be a simple, finite, undirected graph with vertex set {$$v_1,...,v_n$$}. Let $$\Delta(G)$$ denote the maximum degree of G and let N = {1, 2, ...} denote the set of all possib...

Graph G is obtained by adding vertex s to K 3,4 and making s adjacent to every vertex of K 3,4 . The minimum number of colours required to edge-colour G is _____.

The $${2^n}$$ vertices of a graph $$G$$ correspond to all subsets of a set of size $$n$$, for $$n \ge 6$$. Two vertices of $$G$$ are adjacent if and only if the corresponding sets...
