Leomarich Fortugaliza Casinillo, Emily L. Casinillo · Annals of Mathematics and Computer Science · 2025
In this paper, we introduce and investigate a new variant of a Roman dominating function in graphs called outer-connected fair Roman dominating function. In addition, we presented some theoretical properties of outer-connected fair Roman dominating functions in some classes of connected graphs and discussed some important results.
