A note on "symmetric" vielbeins in bimetric, massive, perturbative and non perturbative gravities

Cedric Deffayet, Jihad Mourad, George Zahariade

We consider a manifold endowed with two different vielbeins $E^A{}_{\mu }$ and $L^A{}_{\mu }$ corresponding to two different metrics $g_{\mu \nu }$ and $f_{\mu \nu }$. Such a situation arises generi…
