Query: Dilaton gravity (with a Gauss-Bonnet term) derived from five-dimensional
  Chern-Simons gravity   We study the problem of boundary terms and boundary conditions for
Chern-Simons gravity in five dimensions. We show that under reasonable boundary
conditions one finds an effective field theory at the four-dimensional boundary
described by dilaton gravity with a Gauss-Bonnet term. The coupling of matter
is also discussed.
