A positive integer n is called super totient if the residues of n
which are prime to n can be partitioned into two disjoint subsets of equal
sums. Let G be a given graph with V, the set of vertices and E is the set of
its edges. An injective function g defined on V into subset of integers will
be termed as super totient labeling of the graph G, if the function g
∗
: E →
N defined by g
∗
(xy) = g(x)g(y) assigns a super totient number for all
edges xy ∈ E, where x, y ∈ V. A graph admits this labeling is called
a super totient graph. In the current manuscript, the authors investigate a
novel labeling algorithm, called super totient labeling, for several classes
of graphs such as friendship graphs, wheel graphs, complete graphs and
complete bipartite graphs.
