## Abstract An old conjecture of ErdΕ‘s states that there exists an absolute constant __c__ and a set __S__ of density zero such that every graph of average degree at least __c__ contains a cycle of length in __S__. In this paper, we prove this conjecture by showing that every graph of average degre

Bondy and Vince proved that every graph with minimum degree at least three contains two cycles whose lengths differ by one or two, which answers a question raised by Erdo ˝s. By a different approach, we show in this paper that if G is a graph with minimum degree d(G) \ 3k for any positive integer k,

Mader proved that every 2-connected simple graph G with minimum degree d exceeding three has a cycle C, the deletion of whose edges leaves a 2-connected graph. Jackson extended this by showing that C may be chosen to avoid any nominated edge of G and to have length at least d-1. This article proves

In this note we prove that every 2-connected graph of order n with no repeated cycle lengths has at most n + 2(n -2) -1 edges and we show this result is best possible with the correct order of magnitude on √ n. The 2connected case is also used to give a quick proof of Lai's result on the general cas
