Total Irregularity of Indu-Bala Product of Graphs
Total Irregularity of Indu-Bala Product of Graphs
The total irregularity of a simple undirected graph G is defined as , 1 2 t G G u v V G irr G d u d v , where G d u denotes the degree of a vertex u V G . The Indu-Bala product of G1 and G2 is denoted by G G 1 2 and is obtained from two disjoint copies of the join G G 1 2 of G1 and G2 by joining the corresponding vertices in the two copies of G2 . In this paper, the total irregularity of G G 1 2 is obtained in terms of the total irregularities of G1 and G2 .
