Scientific paper

We study the motion of global degrees of freedom in (2+1)-dimensional
Einstein gravity with a cosmological constant by a perturbation method.
We find that the moduli parameters of the higher-genus two-surfaces move
along geodesic curves and stop asymptotically as the three-dimensional
universe expands.
