SUMMARY:Mamadou Moustapha Kanté\, Strongly flip-flat classes of graphs
DESCRIPTION:Strong flip-flatness appears to be the analogue of uniform almost-wideness in the setting of dense classes of graphs. Almost-wideness is a notion that was central in different characterisations of nowhere dense classes of graphs\, and in particular the game-theoretic one. In this talk I will present the flip-flatness notions and conjectures about the characterization of strongly flip-flat graph classes. Then\, I will present a proof that strongly flip-flat classes of graphs that are weakly sparse are indeed uniformly almost-wide\, making a step towards their characterisation. A consequence is a characterization of strongly flip-flat graph classes with low rank-depth colourings. \nThis is a joint work with F. Ghasemi\, J. Grange and F. Madelaine.
