Description
We analyse the non-linear frame field theory of conformal
higher spins in three dimensions via its Chern-Simons
formulation. Its relation to the metric formulation is
explained. The full non-linear spin 3 Cotton equation with
spin 4 fields and higher truncated away is derived. The
coupling to scalar fields (AdS4 singletons) is given in
terms of a star product unfolded equation. The reason for
studying theories of this kind come from AdS4/CFT3 with
Neumann boundary conditions for gauge fields in AdS4.
