Superfield Description of a Self-Dual Supergravity a la MacDowell-Mansouri
J. A. Nieto
Using MacDowell-Mansouri theory, in this work, we investigate a superfield description of the self-dual supergravity a la Ashtekar. We find that in order to reproduce previous resu…

Towards an Ashtekar Formalism in Twelve Dimensions
J. A. Nieto
We discuss the Ashtekar formalism from the point of view of twelve dimensions. We first focus on the 2+10 spacetime signature and then we consider the transition $2+10\to (2+2)+(0+…

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…
