Pre-metric two-form gravity — •Florian Wolz — Friedrich-Alexander-Universität, Erlangen, Deutschland

Within the constructive gravity program it was shown that predictive and quantizable matter field theories pose such strong conditions on the underlying geometry that its Lagrangian is completely determined. Building on this program efforts have been made to derive the Lagrangian of pre-metric geometry.

After both, the weak field limit and the symmetry reduced case of birefringent cosmology, were successfully derived, in this talk we now employ a first order formulation of pre-metric geometry constructed with 2-forms in order to obtain an exact solution of the pertinent gravitational closure equations.
