Quotient-3 Cordial Labeling for Some Special Graphs - Part-II

Abstract

Let G be a graph of order p and size q. Let f: V (G) → Z 4 -{0} be a function. For each E (G) define f*: E (G) → Z 3 by f*(uv) =

Quotient Labeling of Corona of Ladder Graphs

“…Quotient labeling of graphs was first introduced by P. Sumathi and A. Rathi [2]. They found the quotient labeling number of various graphs and are found in [3][4][5]. In this paper we found the quotientlabeling number of corona of family of ladder graphs.…”
