چکیده
The prism over a graph G is the Cartesian product of with complete K2. A hamiltonian if there exists spanning cycle in G, and prism-hamiltonian hamiltonian. Rosenfeld Barnette (1973) [15] conjectured that every 3-connected planar prism-hamiltonian. We construct counterexample to conjecture.

Hamiltonicity in 3-connected claw-free graphs
Kuipers and Veldman conjectured that any 3-connected claw-free graph with order ν and minimum degree δ ≥ ν+6 10 is Hamiltonian for ν sufficiently large. In this paper, we prove that if H is a 3-connected claw-free graph with sufficiently large order ν, and if δ(H) ≥ ν+5 10 , then either H is hamiltonian, or δ(H) = ν+5 10 and the Ryjác̆ek’s closure cl(H) of H is the line graph of a graph obtained...
متن کاملHamiltonicity of 3-connected line graphs
Thomassen conjectured that every 4-connected line graph is Hamiltonian. Lai et al. conjectured [H. Lai, Y. Shao, H. Wu, J. Zhou, Every 3-connected, essentially 11-connected line graph is Hamiltonian, J. Combin. Theory Ser. B 96 (2006) 571–576] that every 3-connected, essentially 4-connected line graph is Hamiltonian. In this note, we first show that the conjecture posed by Lai et al. is not tru...
متن کاملHamiltonicity in connected regular graphs
In 1980, Jackson proved that every 2-connected k-regular graph with at most 3k vertices is Hamiltonian. This result has been extended in several papers. In this note, we determine the minimum number of vertices in a connected k-regular graph that is not Hamiltonian, and we also solve the analogous problem for Hamiltonian paths. Further, we characterize the smallest connected k-regular graphs wi...
متن کاملHamiltonicity of Cubic 3-Connected k-Halin Graphs
We investigate here how far we can extend the notion of a Halin graph such that hamiltonicity is preserved. Let H = T ∪ C be a Halin graph, T being a tree and C the outer cycle. A k-Halin graph G can be obtained from H by adding edges while keeping planarity, joining vertices of H − C, such that G − C has at most k cycles. We prove that, in the class of cubic 3-connected graphs, all 14-Halin gr...
متن کاملHamiltonicity of 3-connected generalized bull-free line graphs
For graphs G and H, G is said to be H-free if G has no induced subgraph isomorphic to H. For integers s and t with 1 ≤ s ≤ t, let Bs,t be a graph obtained by attaching each of some two distinct vertices of a triangle to an end vertex of one of two vertex-disjoint paths of orders s and t. In this paper, we prove that every 3-connected Bs,9−s-free line graph is Hamiltonian for an integer s with 1...
