Reconfiguration graphs of mutual-visibility sets

Julián A. Fresán-Figueroa, Ilán A. Goldfeder, Aldo Lozano-Piña

A set $S \subseteq V (G)$ is a mutual-visibility set if every pair of vertices in $S$ is joined by a geodesic whose internal vertices do not belong to $S$ . We define a reconfiguratio…

Alternating Hamiltonian cycles in $2$ -edge-colored multigraphs

Alejandro Contreras-Balbuena, Hortensia Galeana-Sánchez, Ilan A. Goldfeder

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…
