On irregularity strength of disjoint union of friendship graphs

Ali Ahmad, Martin Baca, Muhammad Numan


We investigate the vertex total and edge total modication of the well-known irregularity strength of graphs. We have determined the exact values of the total vertex irregularity strength and the total edge irregularity strength of a disjoint union of friendship graphs.
