摘要
In this paper, first we prove that any graph G is 2-connected if diam(G) <= g - 1 for even girth g, and for odd girth g and maximum degree Delta <= 2 delta - 1 where delta is the minimum degree. Moreover, we prove that any graph G of diameter diam(G) <= g - 2 satisfies that (i) G is 5-connected for even girth g and Delta <= 2 delta - 5, and (ii) G is super-kappa for odd girth g and Delta <= 3 delta/2 - 1.
