Main Article Content
Abstract
Let be a connected graph and be a -convex set of A subset is called a forcing subset for if is the unique -convex set containing A forcing subset for of minimum cardinality is a minimum forcing subset of . The forcing triangle free detour convexity number () of is the minimum cardinality among the forcing subset for and the forcing triangle free detour convexity number ) of is the minimum forcing triangle free detour convexity number among all triangle free detour convex set of Some general properties satisfied by this concept are studied. The forcing triangle free detour convexity numbers of certain classes of graphs are determined. It is shown for every pair of integers with and , there exists a connected graph such that and
