$(k, H)$ -kernels in nearly tournaments

Hortensia Galeana-Sánchez, Miguel Tecpa-Galván

Let $H$ be a digraph possibly with loops, $D$ a digraph without loops, and $ρ : A (D) \to V (H)$ a coloring of $A (D)$ ( $D$ is said to be an $H$ -colored digraph). If $W=(x_{0},…

Pancyclism in the Generalized Sum of Digraphs

Narda Cordero-Michel, Hortensia Galeana-Sánchez

A digraph $D = (V, A)$ of order $n \geq 3$ is pancyclic, whenever $D$ contains a directed cycle of length $k$ for each $k \in {3, ..., n}$ ; and D is vertex-pancyclic iff, for each vertex…

Vertex-Pancyclism in the Generalized Sum of Digraphs

N. Cordero-Michel, H. Galeana-Sánchez

A digraph $D = (V (D)$ , $A (D))$ of order $n \geq 3$ is pancyclic, whenever $D$ contains a directed cycle of length $k$ for each $k \in {3, \dots, n}$ ; and $D$ is vertex-pancyclic iff,…

Vertex Alternating-Pancyclism in 2-Edge-Colored Graphs

Narda Cordero-Michel, Hortensia Galeana-Sánchez

An alternating cycle in a 2-two-edge-colored graph is a cycle such that any two consecutive edges have different colors. Let $G_{1}, \dots, G_{k}$ be a collection of pairwise vertex d…

Panchromatic patterns by paths

Germán Benítez-Bobadilla, Hortensia Galeana-Sánchez, César Hernández-Cruz

Let $H = (V_{H}, A_{H})$ be a digraph, possibly with loops, and let $D = (V_{D}, A_{D})$ be a loopless multidigraph with a colouring of its arcs $c : A_{D} \to V_{H}$ . An $H$ -path of $D$ is…

Semi-Grundy function, an hereditary approach to Grundy function

Hortensia Galeana-Sánchez, Raúl González-Silva

Grundy functions have found many applications in a wide variety of games, in solving relevant problems in Game Theory. Many authors have been working on this topic for over many ye…
