List edge and list total colorings of planar graphs without non-induced 7-cycles

Authors: Aijun Dong ; Guizhen Liu ; Guojun Li

Giving a planar graph G, let χ'l(G) and χ''l(G) denote the list edge chromatic number and list total chromatic number of G respectively. It is proved that if G is a planar graph without non-induced 7-cycles, then χ'l(G)≤Δ(G)+1 and χ''l(G)≤Δ(G)+2 where Δ(G)≥7.
