Abstract: (arXiv)
We study conformal gravity in d=2+1, where the Cotton tensor is equated to a--necessarily traceless--matter stress tensor, for us that of the improved scalar field. We first solve this system exactly in the wave regime, then show it to be equivalent to topologically massive gravity.Note:
