Abstract

A graph is 1-planar if it can be drawn on the plane so that each edge is crossed by at most one other edge. In this paper, it is proved that each 1-planar graph with maximum degree Δ is (Δ+1)-edge-choosable and (Δ+2)-total-choosable if Δ ⩾ 16, and is Δ-edge-choosable and (Δ+1)-total-choosable if Δ ⩾ 21. The second conclusion confirms the list coloring conjecture for the class of 1-planar graphs with large maximum degree.
