In this paper we study the ultimate independence ratio I(G) of a graph G, which is defined as the limit of the sequence of independence ratios of powers of G. We construct a graph G with ultimate independence ratio I(G) strictly between the previous known upper bound 1/zz(G) and lower bound 1/x(G).

## Abstract This paper presents some recent results on lower bounds for independence ratios of graphs of positive genus and shows that in a limiting sense these graphs have the same independence ratios as do planar graphs. This last result is obtained by an application of Menger's Theorem to show t
We investigate the limiting behaviour of the independence ratio of increasing Cartesian powers of a graph.
A new lower bound on the independence number of a graph is established and an accompanying efficient algorithm constructing an independent vertex set the cardinality of which is at least this lower bound is given. (~

For graphs G and H, the Cartesian product G × H is defined as follows: the vertex set is ## V(G) × V(H), and two vertices (g,h) and (9',h') are adjacent in G × H if either g = g' and hh' E E(H) or h = h' and g9' E E(G). Let G k denote the Cartesian product of k copies of G. The chromatic differen
