Total Eccentricity of some Graph Operations

Let G be a simple connected graph. The total eccentricity of a graph G,ζ(G), is defined as ζ(G)=∑v∈V(G)ecG(v), where ecG(v) of a vertex v∈V(G) is the maximum distance between v and any other vertex in G. In this paper, the total eccentricity of some graph operations are computed and then a bound for that of tensor product is presented.
