Hamiltonians for a general dilaton gravity theory on a spacetime with a   non-orthogonal, timelike or spacelike outer boundary
  A generalization of two recently proposed general relativity Hamiltonians, to the case of a general (d+1)-dimensional dilaton gravity theory in a manifold with a timelike or spacelike outer boundary, is presented.
