Perturbative expansion of area metric gravity to second order in the equations of motion (third order in the lagrangian). Building up on the paper on covariant constructive gravity. This repository contains:
- A Haskell application generating Lorentz invariant expansion coefficients and solving the diffeomorphism covariance equations perturbatively
- Cadabra code using the results from the Haskell application, performing a 3+1 split of the Lagrangian and deriving the corresponding field equations
- Maple and Mathematica code for further inspection of the field equations
