Some papers say that Palatini Formalism still works if the frame variables [tex]e^i_a[/tex]

is not an isomorphism (from tangent bundle to frame bundle), this generalizes GR to include the cases of degenerate metric.

But one could not derive the Einstein's Equation if [tex]e^i_a[/tex] is not an isomorphism!!

Somebody please explain to me how it works?
