Linearized Five Dimensional Kaluza-Klein Theory as a Gauge Theory
G. Atondo-Rubio, J. A. Nieto, L. Ruiz +1
We develop a linearized five dimensional Kaluza-Klein theory as a gauge theory. By perturbing the metric around flat and the De Sitter backgrounds, we first discuss linearized grav…

Hamiltonian Noether theorem for gauge systems and two time physics
V. M. Villanueva, J. A. Nieto, L. Ruiz +1
The Noether theorem for Hamiltonian constrained systems is revisited. In particular, our review presents a novel method to show that the gauge transformations are generated by the…
