AbstractThe List Edge Colouring Conjecture asserts that, given any multigraphG with chromatic indexk and any set system {Se:e∈E(G)} with each |Se|=k, we can choose elementsse∈Sesuch thatse≠sfwhenevere andf are adjacent edges. Using a technique of Alon and Tarsi which involves the graph monomial
$$prod {left{ {xu - x_upsilon :uupsilon in E}
ight}}$$
of an oriented graph, we verify this conjecture for certain families of 1-factorable multigraphs, including 1-factorable planar graphs.
