Long-eared digraphs

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

Let $H$ be a subdigraph of a digraph $D$ . An ear of $H$ in $D$ is a path or a cycle in $D$ whose ends lie in $H$ but whose internal vertices do not. An \emph{ear decomposition} of…

About $(k, l)$ -kernels, semikernels and Grundy functions in partial line digraphs

Camino Balbuena, Hortensia Galeana-Sánchez, Mukuy-kak Guevara

Let $D = (V, A)$ be a digraph and consider an arc subset $A^{'} \subseteq A$ and an exhaustive mapping $ϕ : A \to A^{'}$ such that $(i)$ the set of heads of $A^{'}$ is $H (A^{'}) = V$ ; $(ii)$ the map f…
