摘要：A Coxeter polytope in the spherical, hyperbolic or Euclidean space is a polytope whose dihedral angles are all integer submultiples of π. Already in 1934, H. S. M. Coxeter has classified spherical and Euclidean Coxeter polytopes. However, the classification of hyperbolic Coxeter polytopes in dimension at least four is still far from being done. We will talk about hyperbolic Coxeter polytopes with few facets. This will involve joint work with Fangting Zheng.
