The Forcing Connected Edge Monophonic Number of a Graph
Subscribe/Renew Journal
Let M be a minimum connected edge monophonic set of G. A subset T ⊆ M is called a forcing subset for M if M is the unique minimum connected edge monophonic set containing T. A forcing subset for M of minimum cardinality is a minimum forcing subset of M. The forcing connected edge monophonic number of M, denoted by fm1c(M), is the cardinality of a minimum forcing subset of M. The forcing connected edge monophonic number of G, denoted by fm1c(G), is fm1c(G) = min{fm1c(M)}, where the minimum is taken over all minimum connected edge monophonic set M in G. It is shown that for every integers a and b with a < b, and − 2 − 2 > 0, there exists a connected graph G such that, fm1c(G) = a and m1c(G) = b , where m1c (G) is the connected edge monophonic number of a graph G.
