Wolfgang Kummer was a pioneer of two-dimensional gravity and a strong advocate of the first order formulation in terms of Cartan variables. In the present work we apply Wolfgang Kummers philosophy, the Vienna School approach, to a specific three-dimensional model of gravity, cosmological topologically massive gravity at the chiral point. Exploiting a new ChernSimons representation we perform a canonical analysis. The dimension of the physical phase space is two per point, and thus the theory exhibits a local physical degree of freedom, the topologically massive graviton. ...
