Moon and Moser in 1963 conjectured that if G is a 3-connected planar graph on n vertices, then G contains a cycle of length at least Oðn log 3 2 Þ: In this paper, this conjecture is proved. In addition, the same result is proved for 3-connected graphs embeddable in the projective plane, or the torus

Abstract
In this article, we apply a cutting theorem of Thomassen to show that there is a function f: N → N such that if G is a 3‐connected graph on n vertices which can be embedded in the orientable surface of genus g with face‐width at least f(g), then G contains a cycle of length at least cn, where c is a constant not dependent on g. © 2002 Wiley Periodicals, Inc.

We generalize Kasteleyn's method of enumerating the perfect matchings in a planar graph to graphs embedding on an arbitrary compact boundaryless 2-manifold S. Kasteleyn stated that perfect matchings in a graph embedding on a surface of genus g could be enumerated as a linear combination of 4 g Pfaff
## Abstract In this paper, we show that every 3‐connected claw‐free graph on n vertices with δ ≥ (__n__ + 5)/5 is hamiltonian. © 1993 John Wiley & Sons, Inc.
## Abstract We show that every __k__‐connected graph with no 3‐cycle contains an edge whose contraction results in a __k__‐connected graph and use this to prove that every (__k__ + 3)‐connected graph contains a cycle whose deletion results in a __k__‐connected graph. This settles a problem of L. Lo
Let \(G\) be a 3-connected \(K_{1, d}\)-free graph on \(n\) vertices. We show that \(G\) contains a 3-connected spanning subgraph of maximum degree at most \(2 d-1\). Using an earlier result of ours, we deduce that \(G\) contains a cycle of length at least \(\frac{1}{2} n^{c}\) where \(c=\left(\log
## Abstract A necessary and sufficient condition is obtained for a set of 12 vertices in any 3‐connected cubic graph to lie on a common cycle.
