Total Irregularity of Indu-Bala Product of Graphs

The total irregularity of a simple undirected graph is defined as , where denotes the degree of a vertex . The Indu-Bala product of and is denoted by and is obtained from two disjoint copies of the join of and by joining the corresponding vertices in the two copies of . In this paper, the total irregularity of is obtained in terms of the total irregularities of and
