DESCRIPTION:Ruth Kellerhals\, Fribourg\nIn the focus are hyperbolic Coxete
 r groups\nof finite covolume. These are groups generated by finitely\nmany
  reflections in the facets of a finite volume\nhyperbolic n-polyhedron who
 se dihedral angles are\nsubmultiples of pi.\nFirst\, I shall present the m
 ost important features and\ndiscuss their natural appearance in the realm 
 of\nhyperbolic orbifolds of small volume.\nOf particular arithmetic intere
 st are growth properties\nof Coxeter groups acting with finite covolume on
 \nhyperbolic spaces of small dimensions.\nIn the second half\, I shall pre
 sent some recent results.
