Pure Maths Colloquium: Geometry of non-discrete groups
29 January 2001 16:00 in CM221
"In this talk we will investigate hyperbolic, spherical, and Euclidean orbifolds and cone-manifolds. A geometrical approach for constructing fundamental polyhedra for cone-manifolds through their discrete and non-discrete holonomy groups is consided. We establish trigonometric identities for cone-angles and lengths of singular geodesics. Explicit formulae for volumes and isoperimetric inequalities for knot and link orbifolds will also be given."
