Asymptotically optimal bound on the adjacent vertex distinguishing edge choice number

Abstract

An adjacent vertex distinguishing edge colouring of a graph GG without isolated edges is its proper edge colouring such that no pair of adjacent vertices meets the same set of colours in GG. We show that such colouring can be chosen from any set of lists associated to the edges of GG as long as the size of every list is at least Δ+CΔ12(logΔ)4\Delta+C\Delta^{\frac{1}{2}}(\log\Delta)^4, where Δ\Delta is the maximum degree of GG and CC is a constant. The proof is probabilistic. The same is true in the environment of total colourings.
