On the list dynamic coloring of graphs

WebA dynamic ‘-list coloring of a graph is a proper coloring so that each vertex receives a color from a list of ‘ distinct candidate colors assigned to it, and meanwhile, there are at least two colors appearing in the neighborhood of every vertex of degree at least two.
