Three counterexamples to a conjecture of Colin de Verdière on multiplicity
Maxime Fortier Bourque, Émile Gruda-Mediavilla, Bram Petri +1
We exhibit closed hyperbolic surfaces of genus , , and such that the multiplicity of the first nonzero eigenvalue of their Laplacian is larger than the maximum conject…

Failure of the well-rounded retract for Outer space and Teichmüller space
Maxime Fortier Bourque
The well-rounded retract for is defined as the set of flat tori of unit volume and dimension whose systoles generate a finite-index subgroup in homo…

Linear programming bounds for hyperbolic surfaces
Maxime Fortier Bourque, Bram Petri
We adapt linear programming methods from sphere packings to closed hyperbolic surfaces and obtain new upper bounds on their systole, their kissing number, the first positive eigenv…
