Show affiliationsIn (2+1)-dimensional gravity without matter, a spacetime is represented by a (pseudo-) Riemannian manifold of constant curvature. Though locally trivial, it can have a rich geometric structure, which is completely described by holonomy. The authors extracts an invariant of geometric structure out of holonomy. The author also shows an explicit construction of holonomy for hyperbolic manifolds which represent quantum nucleation of the universe in (2+1)-dimensional gravity.
