Abstract: We calculate the running of the three coupling constants in cosmological,topologically massive 3d gravity. We find that u, the dimensionlesscoefficient of the Chern-Simons term, has vanishing beta function. The flow ofthe cosmological constant and Newton-s constant depends on u, and for anypositive u there exist both a trivial and a nontrivial fixed point.
