Renormalization of the Einstein-Cartan Theory in First-Order Form
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We examine the Einstein-Cartan (EC) theory in first-order form, which has a diffeomorphism as well as a local Lorentz invariance. We study the renormalizability of this theory in t…

Field redefinition invariant Lagrange multiplier formalism with gauge symmetries
D. G. C. McKeon, F. T. Brandt, S. Martins-Filho
It has been shown that by using a Lagrange multiplier field to ensure that the classical equations of motion are satisfied, radiative effects beyond one-loop order are eliminated.…
