Contractions of Filippov algebras
J. A. de Azcarraga, J. M. Izquierdo, M. Picon
We introduce in this paper the contractions of -Lie (or Filippov) algebras and show that they have a semidirect structure as their Lie alge…
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…
Single twistor description of massless, massive, AdS, and other interacting particles
Itzhak Bars, Moises Picon
The Penrose transform between twistors and the phase space of massless particles is generalized from the massless case to an assortment of other particle dynamical systems, includi…
Twistor Transform in d Dimensions and a Unifying Role for Twistors
Itzhak Bars, Moises Picon
Twistors in four dimensions d=4 have provided a convenient description of massless particles with any spin, and this led to remarkable computational techniques in Yang-Mills field…
Generalized curvature and the equations of D=11 supergravity
I. A. Bandos, J. A. de Azcarraga, M. Picon +1
It is known that, for zero fermionic sector, the bosonic equations of Cremmer-Julia-Scherk eleven-dimensional supergravity can be collected in a compact expression which is a condi…
On the formulation of D=11 supergravity and the composite nature of its three-from field
Igor A. Bandos, Jose A. de Azcarraga, Moises Picon +1
The underlying gauge group structure of the D=11 Cremmer-Julia-Scherk supergravity becomes manifest when its three-form field A_3 is expressed through a set of one-form gauge field…
