(2)-pancyclic graphs

open access: yesDiscrete Applied Mathematics, 2013
We introduce the class of (2)-pancyclic graphs, which are simple undirected finite connected graphs of order n having exactly two cycles of length p for each p satisfying [email protected][email protected]?n, analyze their properties, and give several examples of such graphs, among which are the smallest.

On pancyclism of hamiltonian graphs

open access: yesElectronic Notes in Discrete Mathematics, 2000
Abstract Let n and Δ be two integers with Δ ≤ n − 1. We study the set of cycle lengths occurring in any hamiltonian graph G of order n and maximum degree Δ. We show that for the case n/2+1 ≤ Δ ≤ 2n-2/3 this set contains all the integers belonging to the union [3, 2Δ-n+2] ∪ [n-Δ+ 2,Δ+1], and for 2n−2 3 ≤ Δ ≤ n − 1 it contains every integer ...

A SUFFICIENT CONDITION FOR PANCYCLIC GRAPHS

open access: yesBulletin of the Australian Mathematical Society
Abstract A graph G is called an $[s,t]$ -graph if any induced subgraph of G of order s has size at least $t.$ We prove that every $2$ -connected $[4,2]$ -graph of order at least $7$ is pancyclic.
