摘 要：

As a generalization of list coloring, DP-coloring of graphs was introduced by Dvoˇr´ak and Postle in 2015. Recently, Bernshteyn and Kostochka introduced edge DP-coloring of graphs which is naturally corresponding to the DP-coloring of their line graphs. In this paper, we will present some recent results on edge DP-coloring and signed edge coloring (a special edge DP-coloring) of planar graphs.
