Abstract
We study topology-changing processes in (2+1)-dimensional quantum gravity with a negative cosmological constant. By playing the "gluing-many-polyhedra game" for hyperbolic geometry, we explicitly construct an infinite number of different instantonlike solutions. These solutions can be used to evaluate various topology-changing amplitudes in the WKB approximation.Keywords
