First order formalism for bimetric theories with connection interaction

Abstract

We construct a first order Lagrangian formalism for bimetric theories with an interaction which is a general function of metrics and their derivatives, including non-analytic functions. The first-order actions are fully equivalent to the original actions, with the same field equations for the metrics.
