Query: Quantization of diffeomorphism invariant theories of connections with
  local degrees of freedom   Quantization of diffeomorphism invariant theories of connections is studied.
A solutions of the diffeomorphism constraints is found. The space of solutions
is equipped with an inner product that is shown to satisfy the physical reality
conditions. This provides, in particular, a quantization of the
Husain-Kucha\v{r} model. The main results also pave way to quantization of
other diffeomorphism invariant theories such as general relativity. In the
Riemannian case (i.e., signature ++++), the approach appears to contain all the
necessary ingredients already. In the Lorentzian case, it will have to combined
in an appropriate fashion with a coherent state transform to incorporate
complex connections.
