Maximum and maximal roman free functions


Author(s): DK Thakkar and SM Badiyani

Abstract: In this paper we consider Maximum Roman Free Functions and Maximal Roman Free Function with minimum cardinality. We consider the change in the Roman Free Number and an rf-number of a graph when a vertex is removed from the graph. We prove a necessary and sufficient condition under which the Roman Free Number of a graph increases. Also we prove a necessary and sufficient conditions under which the rf-number of a graph increases or decreases.
