Abstract:
In this note a new measure of irregularity of a graph G is introduced. It is
named the total irregularity of a graph and is defined as irrt(G) = 1 / 2∑u,v
∈V(G) |dG(u)-dG(v)|, where dG(u) denotes the degree of a vertex u ∈V(G). All
graphs with maximal total irregularity are determined. It is also shown that
among all trees of the same order the star has the maximal total irregularity.
