On ADEG-polyhedra in hyperbolic spaces

In this talk, we discuss the classification of hyperbolic Coxeter polyhedra in dimensions beyond 3. After a brief overview of known classification results, we present a bound for the dihedral angles of Coxeter polyhedra with mutually intersecting facets, together with a recipe to classify them all. We provide a new Coxeter polyhedron in dimension 9 and complete the classification of ADEG-polyhedra.
