Tournaments with maximal decomposability

Cherifa Ben Salha

Given a tournament $T$ , a module of $T$ is a subset $M$ of $V (T)$ such that for $x, y \in M$ and $v \in V (T) ∖ M$ , $(x, v) \in A (T)$ if and only if $(y, v) \in A (T)$ . The trivial…

Decomposability and co-modular indices of tournaments

Houmem Belkhechine, Cherifa Ben Salha

Given a tournament $T$ , a module of $T$ is a subset $X$ of $V (T)$ such that for $x, y \in X$ and $v \in V (T) ∖ X$ , $(x, v) \in A (T)$ if and only if $(y, v) \in A (T)$ . The trivial…
