    Massive gravity - Corrections to the Pauli Fierz mass term

    I'm using the same ansatz for f as they do in the paper. Does this look right so far? I can post the non vanishing components of the EMT soon if necessary. Note i achieved the EMT by varying the mass term with respect to the inverse of f. L_{Mass}=\frac{-M^2\sqrt{-\eta}}{4k_{f}^2} \left ( (f^{...

    Massive gravity - Corrections to the Pauli Fierz mass term

    Homework Statement I'm looking at solving a simple theory of massive gravity for Scwarzchild type solutions. I've attatched the paper that I'm working with. I've tried to add the 3 possible cubic terms to L_mass parametrized by constants. It doesn't seem possible to solve for B as a function of...

    Tensor Variation with Respect to Metric in First Order Formalism

    Homework Statement I'm just wondering if I'm doing this calculation correct? eta and f are both tensors Homework EquationsThe Attempt at a Solution \frac{\delta \left ( \gamma_{3}f{_{\lambda}}^{k}f{_{k}}^{\sigma}f{_{\sigma}}^{\lambda} \right )}{\delta f^{\mu\nu}}=\frac{\delta\left (\gamma_{3}...
