Abstract:Consider a graph urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0001 of minimum degree δ and order n. Its total vertex irregularity strength is the smallest integer k for which one can find a weighting urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0002 such that urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0003 for every pair urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0004 of vertices of G. We prove that the total vertex irregularity strength of graphs with urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0005 is bounded from above by urn:x-wiley:03649024:media:jgt21748:jgt21748-math-0006. One of the cornerstones of the proof is a random ordering of the vertices generated by order statistics.
