摘要
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, we verify the total coloring conjecture for every 1-planar graph G if either ?(G) ≥ 9 and g(G) ≥ 4, or ?(G) ≥ 7 and g(G) ≥ 5, where ?(G) is the maximum degree of G and g(G) is the girth of G.
