Edge-Colouring Geometric Complete Graphs ★★
Author(s): Hurtado
Question What is the minimum number of colours such that every complete geometric graph on vertices has an edge colouring such that:
- \item[Variant A] crossing edges get distinct colours, \item[Variant B] disjoint edges get distinct colours, \item[Variant C] non-disjoint edges get distinct colours, \item[Variant D] non-crossing edges get distinct colours.
