Euclidean simplices generating discrete reflection groups
Let be a convex polytope in the Euclidean space \E^n.
Consider the group generated by reflections in the facets of . We
say that {\it generates a reflection group }. In the present paper, we
list all Euclidean simplices generating discrete reflection groups.Comment: 20 pages; MPIM preprin
Coxeter Decompositions of Hyperbolic Tetrahedra
We classify Coxeter decompositions of hyperbolic tetrahedra, i.e. simplices
in the hyperbolic space H^3. The paper completes the classification of Coxeter
decompositions of hyperbolic simplices.Comment: 14 pages, 4 figures, 3 table
