Sum Divisor Cordial Labeling for Middle Graph and Total Graph of Some Graphs
摘要
Graph labeling is one of the most interesting concepts in graph theory which has a numerous application in different fields. A labeling of graph is the allocation of labels, conventionally reserved as integers, to edges and/or nodes of a graph. Sum divisor cordial labeling is a new variant of divisor cordial labeling. In the present investigations we have derived six new out-turns admitting SDCL for middle graph of path, cycle and star, total graph of path, cycle and star graph.
