摘要：

The discussion in a previous paper on reducing the phase space of the first-order Einstein gravity in 2 + 1 dimensions is refined. We provide a preSCription to construct a ''correct'' physical phase space in the case of a positive cosmological constant. A parametrization which unifies the two sectors of the physical phase space is also given. Unlike the cases of a nonpositive cosmological constant, the unified phase space turns out to be Hausdorff type when the cosmological constant is positive.
