Expansions of algebras and superalgebras and some applications
J. A. de Azcarraga, J. M. Izquierdo, M. Picon +1
After reviewing the three well-known methods to obtain Lie algebras and superalgebras from given ones, namely, contractions, deformations and extensions, we describe a fourth metho…
On D=11 supertwistors, superparticle quantization and a hidden SO(16) symmetry of supergravity
Igor A. Bandos, Jose A. de Azcarraga, Dmtri P. Sorokin
We consider a covariant quantization of the D=11 massless superparticle in the supertwistor framework. D=11 supertwistors are highly constrained, but the interpretation of their bo…
BPS preons and higher spin theory in D=4, 6, 10
Igor A. Bandos, Jose A. de Azcarraga
We briefly review here the notion of BPS preons, the hypothetical constituents of M-theory, emphasizing its generalization to arbitrary dimensions D and its relation to higher spin…
On dynamical supergravity interacting with super-p-brane sources
Igor A. Bandos, Jose A. de Azcarraga, Jose M. Izquierdo +1
We review recent progress in a fully dynamical Lagrangian description of the supergravity-superbrane interaction. It suggests that the interacting superfield action, when it exists…
On the local symmetries of gravity and supergravity models
Igor A. Bandos, Jose A. de Azcarraga, Jose M. Izquierdo
We present here a detailed analysis of the local symmetries of supergravity in an arbitrary dimension D, both in the component and superfield approaches, using a field-space democr…
