On the stress transit function

Arun Anil, Manoj Changat, Tanja Dravec +5

The stress interval $S (u, v)$ between $u, v \in V (G)$ is the set of all vertices in a graph $G$ that lie on every shortest $u, v$ -path. A set $U \subseteq V (G)$ is stress convex if $S(…

Weakly modular graphs with diamond condition, the interval function and axiomatic characterizations

Lekshmi Kamal Kamalolbhavan-Sheela, Jeny Jacob, Manoj Changat

Weakly modular graphs are defined as the class of graphs that satisfy the \emph{triangle condition ( $T C$ )} and the \emph{quadrangle condition ( $QC$ )}. We study an interesting subcl…
