S. RAVI NARAYANAN*, N. R. SANTHI MAHESWARI

Abstract


In this paper, 2nd-Neighbourly irregular fuzzy graphs and 2nd-Neighbourly totally irregular fuzzy graphs are defined. Comparative study between 2nd-Neighbourly irregular fuzzy graph and 2nd-Neighbourly totally irregular fuzzy graph is done. Property of 2nd-Neighbourly irregular fuzzy graph and 2nd-Neighbourly totally irregular fuzzy graph are discussed. 2nd-Neighbourly irregularity on fuzzy graphs whose underlying graphs are cycle cn, a Barbell graph Bn,m, Sub (Bn,m) are studied.


Keywords


degree of a vertex in fuzzy graph, irregular fuzzy graph, neighbourly irregular fuzzy graph, neighbourly totally irregular fuzzy graph.
