2021 Session 1 : Generalized coloring numbers and friends

The topic of the workshop are Generalized Coloring Numbers: weak and strong coloring numbers, admissibility, centered colorings, low treedepth colorings, connections between these concepts and the notions of bounded expansion and of nowhere denseness, and closely related subjects. We believe that there is a number of very concrete questions that remain open in this area, for instance regarding tight asymptotics of relations between respective parameters. The goal of the workshop would be to identify some of those questions and approach them together or in subgroups.
