Irregular assignments

A weighting of the edges of a graph with integer weights gives rise to a weighting of the vertices, the weight of a vertex being the sum of the weights of its incident edges. An assignment of positive integer weights to the edges of a simple graph G is called irregular if the weighted degrees of the vertices are all different. The irregularity strength is the maximal weight, minimized over all irregular assignments. In this talk I will discuss some recent results and open problems on the irregularity strength of graphs.
