In this paper, we obtain sufficient conditions for the oscillation of the non-autonomous difference equationswhich are the discrete analog of the delay differential equations considered in [1] .
Let G be a 3-connected graph with n vertices, is an independent set of G} , MC(G)=min is an independent set in G}.In this paper, the main results are as follows.TheoremⅠ. If then G is Hamilton-connected.TheoremⅡ. If...
