Abstract
The prism over a graph G is the Cartesian product G □ K~2~ of G with the complete graph K~2~. If the prism over G is hamiltonian, we say that G is prism‐hamiltonian. We prove that triangulations of the plane, projective plane, torus, and Klein bottle are prism‐hamiltonian. We additionally show that every 4‐connected triangulation of a surface with sufficiently large representativity is prism‐hamiltonian, and that every 3‐connected planar bipartite graph is prism‐hamiltonian. © 2007 Wiley Periodicals, Inc.

## Abstract We extend Whitney's Theorem that every plane triangulation without separating triangles is hamiltonian by allowing some separating triangles. More precisely, we define a decomposition of a plane triangulation __G__ into 4‐connected ‘pieces,’ and show that if each piece shares a triangle
We use a construction of A. Bouchet for covering triangulations by means of nowhere-zero dual flows, but slightly modified, to prove that whenever \(G\) is a simple graph, which is not a star, two-cell embedded in a surface \(S\), and \(m\) is a nonnegative integer not divisible by 2,3 , or 5 , ther
In this note we show that, for any surface 7 and any k, there are at most finitely many triangulations of 7 such that each edge is in a noncontractible cycle of length k and is in no shorter noncontractible cycle. Such a triangulation is k-irreducible. This is equivalent to the statement that for an
