List colouring squares of planar graphs (extended abstract)

By Jan van den Heuvel, F Havet, C McDiarmid and B Reed

Abstract

In 1977, Wegner conjectured that the chromatic number of the square of every planar graph G with maximum degree Δ⩾8 is at most View the MathML source. We show that it is at most View the MathML source, and indeed this is true for the list chromatic number
