摘要：

We study topological matter minimally coupled to gravity in 2 + 1 dimensions. We show that the resulting system has a finite-dimensional physical phase space that can be exactly quantized. The model exhibits the mixing of "gravity" and "matter" degrees of freedom, and the impossibility of treating them independently.
