Critical Kernel Imperfectness in -quasi-transitive and -anti-transitive digraphs of small diameter
Germán Benítez-Bobadilla, Hortensia Galeana-Sánchez, César Hernández-Cruz
A kernel in a digraph is an independent and absorbent subset of its vertex set. A digraph is critical kernel imperfect if it does not have a kernel, but every proper induced subdig…
Dynamic cycles in edge-colored multigraphs
Hortensia Galeana-Sánchez, Carlos Vilchis-Alfaro
Let be a graph possibly with loops and be a multigraph without loops. An -coloring of is a function . We will say that is an -colore…
Euler dynamic H-trails in edge-colored graphs
Hortensia Galeana-Sánchez, Carlos Vilchis-Alfaro
Alternating Euler trails has been extensively studied for its diverse applications, for example, in genetic and molecular biology, social science and channel assignment in wireless…
Cycles of length 3 and 4 in edge-colored complete graphs with restrictions in the color transitions
Hortensia Galeana-Sánchez, Felipe Hernández-Lorenzana, Rocío Sánchez-López
Let be an edge-colored graph, a walk in is said to be a properly colored walk iff each pair of consecutive edges have different colors, including the first and the last edg…
