Query: Canonical analysis of cosmological topologically massive gravity at the
  chiral point   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 Kummer's philosophy, the `Vienna School
approach', to a specific three-dimensional model of gravity, cosmological
topologically massive gravity at the chiral point. Exploiting a new
Chern-Simons 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.
