Support Neighbourly Irregular Graphs
Journal Title: International Journal of Scientific Research and Management - Year 2016, Vol 4, Issue 3
Abstract
A new family of irregular graphs namely support n eighbourly irregular graph has been introduced and studied for its properties in this paper. In any graph, the support of a vertex is the sum of degrees of its neighbours. A connected graph G is said to be support neighbourly irregular ( or simply SNI), if no two adjacent vertices in G have same support. A necessary and sufficient condition for a graph to be S NI has been established and the relationship of SNI graphs with other family irregular graphs have been discussed in this paper.
