We prove that if G is a connected graph with p vertices and minimum degree greater than max( p/4 -1,3) then G2 is pancyclic. The result is best possible of its kind.
It is proved that the choice number of every graph G embedded on a surface of Euler genus Ξ΅ β₯ 1 and Ξ΅ = 3 is at most the Heawood number H(Ξ΅) = (7 + β 24Ξ΅ + 1)/2 and that the equality holds if and only if G contains the complete graph K H(Ξ΅) as a subgraph.
In our study of the extremities of a graph, we define a moplex as a maximal clique module the neighborhood of which is a minimal separator of the graph. This notion enables us to strengthen Dirac's theorem : "Every non-clique triangulated graph has at least two non-adjacent simplicial vertices", res
