This means that a graph is dense if the average degree of each vertex is lineal, and sparse if sublineal. Sparsity does not deppend on size. For instance, trees are sparse (because a tree with n nodes has n-1 edges).

Introduction A set of vertices of a graph is independent if the vertices are pairwise nonadjacent. The independence number of a graph G, a (G), is the cardinality of a largest independent set of G. For graph G= (V, E) and A s:- V we let the subgraph of G induced by A, G I A, be the graph with vertices A and edges being those … WebWe obtain new lower bounds for the independence number of K r -free graphs and linear k -uniform hypergraphs in terms of the degree sequence.
