Note on group irregularity strength of disconnected graphs
We investigate the group irregularity strength (sg(G)) of graphs, i.e. the smallest value of s such that taking any Abelian group š¯“– of order s, there exists a function f : E(G) ā†’ š¯“– such that the sums of edge labels at every vertex are distinct. So far it was not known if sg(G) is finite for disconne...
