Abstract

A  (p, q)  graph  G  is said to be a power exponential mean graph if there exist a one to one correspondence  f:V\rightarrow\{1,2,3,\ldots,p\}  such that induced function  f^*:E(G)\rightarrow N  given by

f^* (uv)=\left\lceil{\left({f(u) }^{f(u)}{f(v)}^{f(v)}\right)}^{\frac{1}{f(u)+f(v)}}\right\rceil \qquad \text{or} \qquad f^* (uv)=\left\lfloor{\left({f(u) }^{f(u)}{f(v)}^{f(v)}\right)}^{\frac{1}{f(u)+f(v)}}\right\rfloor

for every  uv\in E(G)  are all distinct. In this paper the power exponential mean labeling of graphs such as path, cycle,  K_1+C_n  for  n  is odd and even, square graph, umbrella  U(m,n), duplicating each vertex by an edge in path  P_n, comb,  C_m\bigodot \overline{ K_1}  and  C_n\bigodot \overline{ K_2}  are discussed.

Keywords: Graph, power exponential mean, path, cycle, square graph, umbrella, comb
