Hyperbolic Coxeter polyhedra with mutually intersecting facets (Naomi Bredon, Université de Fribourg)

05.03.2024 10:30

The classification of hyperbolic Coxeter polyhedra in dimensions beyond 3 is far from being complete. In this talk, we discuss the known classification results and present a method to construct hyperbolic Coxeter polyhedra with mutually intersecting facets. We establish a lower bound for their dihedral angles, and we provide the complete classification of hyperbolic Coxeter polyhedra with mutually intersecting facets and dihedral angles \pi/2, \pi\3 and \pi/6.
