On Non-handlebody Instantons in 3D Gravity
arXiv:0711.2803 · doi:10.1088/1126-6708/2008/09/120
Abstract
In this note we describe the contribution from non-handlebody geometries to the partition function of three-dimensional pure gravity with negative cosmological constant on a Riemann surface of genus greater than one, extending previous considerations for handlebodies.
