A set J C V is called a nonseparating independent set (nsis) of a connected graph G = (V, E), if J is an independent set of G, i.e., E A {uv [ Vu, v E J} = 0, and G -J is connected. We call z(G) = maxJ{lJ[ tJ is an nsis of G} the nsis number of G. Let G be a 3-regular connected graph; we prove that
In this paper, a lower bound on the maximum genus of a graph in terms of its girth is established as follows: let G be a simple graph with minimum degree at least three, and let g be the girth of G. Then ?M(G)~> ~fl(G) + 1 except for G=K4, g-1 where ]~(G) denotes the cycle rank of G and K4 is the co
