In the book by Aldrovandi and Pereria, derivation using the Euler - Lagrange Equation is given in appendix C, page 197. In the last steps of the calculation of energy momentum current, there is some algebraic manipulation involved, which I am not being able to do. Earlier, I tried doing it by...
I tried the variation myself , but the nature of Vierbeins is such that you can get the solution in whatever form you like. There is a sign problem in field equation in various papers , which I am trying to understand. So I need a guide to derive the equations in order to get the full...
