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 ) e c G ( v ) , where e c G ( 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.
