... we are interested in the following question: can we use the functions θ(G),r(G)andd(G )in( 1)insteadofr + (G)? In the common case the answer is negative. The proof is based on the following lemmas. Lemma ... We are interested in studying the functions of the graph G whose values belong to the interval [α(G), χ(G)]. Here α(G) is the size of the largest sta...
