Tree Bijections for Hyperbolic Surfaces

Vortrag von Bart Zonneveld
Datum: 13.06.23   Zeit: 09.30 - 10.30   Raum: Y27H28

Finding bijections to trees, like the Cori-Vauquelin-Schaeffer bijection or the Bouttier-Di Francesco-Guitter bijection, have proven to be important tools for the encoding of (planar) maps. Motivated by this success we can try to step away from discrete maps and try to apply similar techniques to smooth surfaces.

In this talk I will show you my recent work with Timothy Budd and Thomas Meeusen, where we encode genus-0 hyperbolic surfaces using bijections to dressed trees.
