Alternating Hamiltonian cycles in $2$-edge-colored multigraphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2019 A path (cycle) in a $2$-edge-colored multigraph is alternating if no two consecutive edges have the same color. The problem of determining the existence of alternating Hamiltonian paths and cycles in $2$-edge-colored multigraphs is an $\mathcal{NP ...

Hamiltonian Cycles in Cayley Graphs of Gyrogroups
Mathematics, 2022 In this study, we investigate Hamiltonian cycles in the right-Cayley graphs of gyrogroups. More specifically, we give a gyrogroup version of the factor group lemma and show that some right-Cayley graphs of certain gyrogroups are Hamiltonian.

Hamiltonian cycles on bicolored random planar maps
Nuclear Physics B, 2023 We study the statistics of Hamiltonian cycles on various families of bicolored random planar maps (with the spherical topology). These families fall into two groups corresponding to two distinct universality classes with respective central charges c=−1 ...

Decomposing complete 3-uniform hypergraph K_{n}^{(3)} into 7-cycles [PDF]
Opuscula Mathematica, 2019 We use the Katona-Kierstead definition of a Hamiltonian cycle in a uniform hypergraph. A decomposition of complete \(k\)-uniform hypergraph \(K^{(k)}_{n}\) into Hamiltonian cycles was studied by Bailey-Stevens and Meszka-Rosa. For \(n\equiv 2,4,5\pmod 6\)

Hamiltonian Chains in Hypergraphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 Hamiltionian chain is a generalisation of hamiltonian cycles for hypergraphs. Among the several possible ways of generalisations this is probably the most strong one, it requires the strongest structure.

Types of triangle in plane Hamiltonian triangulations and applications to domination and k-walks [PDF]
, 2019 We investigate the minimum number t(0)(G) of faces in a Hamiltonian triangulation G so that any Hamiltonian cycle C of G has at least t(0)(G) faces that do not contain an edge of C.

Enumerating Hamiltonian Cycles [PDF]
The Electronic Journal of Combinatorics, 2014 A dynamic programming method for enumerating hamiltonian cycles in arbitrary graphs is presented. The method is applied to grid graphs, king's graphs, triangular grids, and three-dimensional grid graphs, and results are obtained for larger cases than previously published.

On Hamiltonian Cycles in Claw-Free Cubic Graphs
Discussiones Mathematicae Graph Theory, 2022 We show that every claw-free cubic graph of order n at least 8 has at most 2⌊n4⌋{2^{\left\lfloor {{n \over 4}} \right\rfloor }} Hamiltonian cycles, and we also characterize all extremal graphs.

What do Eulerian and Hamiltonian cycles have to do with genome assembly?
PLoS Computational Biology, 2021 Many students are taught about genome assembly using the dichotomy between the complexity of finding Eulerian and Hamiltonian cycles (easy versus hard, respectively).
