We investigate some properties of graphs whose cycle space has a basis constituted of triangles ('null-homotopic' graphs). We obtain characterizations in the case of planar graphs, and more generally, of graphs not contractible onto Ks. These characterizations involve separating subsets and decompos

It is shown that a 3-connected planar graph with minimum valency 4 is edge-reconstructible if no 4-vertex is adjacent to a 5-vertex. ## 1. Introduction In this paper, all graphs G=(V(G),E(G)) considered will be finite and simple. A connected graph G is said to have connectivity k o = ko(G) if the
## Abstract Carsten Thomassen conjectured that every longest circuit in a 3βconnected graph has a chord. We prove the conjecture for graphs having no __K__~3,3~ minor, and consequently for planar graphs. Β© 2008 Wiley Periodicals, Inc. J Graph Theory 58: 293β298, 2008
