## Abstract Let __G__ be a graph of order __n__ and define __NC(G)__ = min{|__N__(__u__) โˆช __N__(__v__)| |__uv__ โˆ‰ __E__(__G__)}. A cycle __C__ of __G__ is called a __dominating cycle__ or __D__โ€__cycle__ if __V__(__G__) โ€ __V__(__C__) is an independent set. A __D__โ€__path__ is defined analogously.

We present and prove several results concerning the length of longest cycles in 2connected or I-tough graphs with large degree sums. These results improve many known results on long cycles in these graphs. We also consider the sharpness of the results and discuss some possible strengthenings.

Let G be a graph of order n. In this paper, we prove that if G is a 2-connected graph of order n such that for all u, ve V(G), 2 where dist(u,v) is the distance between u and v in G, then either G is hamiltonian, or G is a spanning subgraph of a graph in one of three families of exceptional graphs.
