Diffeomorphism Invariance and Local Lorentz Invariance
Roldao da Rocha, Waldyr A. Rodrigues
We show that diffeomorphism invariance of the Maxwell and the Dirac-Hestenes equations implies the equivalence among different universe models such that if one has a linear connect…
Where are ELKO Spinor Fields in Lounesto Spinor Field Classification?
Roldao da Rocha, Waldyr Alves Rodrigues
This paper proves that from the algebraic point of view ELKO spinor fields belong together with Majorana spinor fields to a wider class of spinor fields, the so-called flagpole spi…
On Conformal d'Alembert-Like Equations
E. Capelas de Oliveira, R. da Rocha
Using conformal coordinates associated with projective conformal relativity we obtain a conformal Klein-Gordon partial differential equation. As a particular case we present and di…
Hidden Consequence of Active Local Lorentz Invariance
W. A. Rodrigues, Roldao da Rocha, J. Vaz
In this paper we investigate a hidden consequence of the hypothesis that Lagrangians and field equations must be invariant under active local Lorentz transformations. We show that…
