Hamiltonian formulation of f(Riemann) theories of gravity

Nathalie Deruelle, Misao Sasaki, Yuuiti Sendouda, Daisuke Yamauchi

We present a canonical formulation of gravity theories whose Lagrangian is an arbitrary function of the Riemann tensor, which, for example, arises in the low-energy limit of superstring theories. Our approach allows a unified treatment of various subcases and an easy identification of the degrees of freedom of the theory.
