New supergravities with central charges and Killing spinors in 2+1 dimensions

P. Howe, J. M. Izquierdo, G. Papadopoulos, P. Townsend
Physics
5 May 1995

Abstract We construct a new class of ( p , q )-extended Poincare supergravity theories in 2+1 dimensions as Chern-Simons theories of supersymmetry algebras with both central and automorphism charges.… Expand

J. A. Azcárraga, J. M. Izquierdo
Physics, Mathematics
1 November 1995

Preface 1. Lie groups, fibre bundles and Cartan calculus 2. Connections and characteristic classes 3. A first look at cohomology of groups and related topics 4. An introduction to abstract group… Expand

Dyonic Membranes

J. M. Izquierdo, N. Lambert, G. Papadopoulos, P. Townsend
Physics
31 August 1995

We present dyonic multi-membrane solutions of the N=2 D=8 supergravity theory that serves as the effective field theory of the T 2-compactified type II su-perstring theory. The 'electric' charge is… Expand

Supersymmetric spacetimes in (2+1) adS-supergravity models

J. M. Izquierdo, P.K.Townsend
Physics
17 January 1995

We find a class of (2+1)-dimensional spacetimes admitting Killing spinors appropriate to (2,0) adS-supergravity. The vacuum spacetimes include anti-de Sitter (adS) space and charged extreme black… Expand

n-ary algebras: a review with applications

J. A. Azcárraga, J. M. Izquierdo
Physics, Mathematics
6 May 2010

This paper reviews the properties and applications of certain n-ary generalizations of Lie algebras in a self-contained and unified way. These generalizations are algebraic structures in which the… Expand

The geometry of branes and extended superspaces

C. Chryssomalakos, J. A. D. Azc'arraga, J. M. Izquierdo, J. C. C. Bueno
Physics, Mathematics
20 April 1999

Abstract We argue that a description of supersymmetric extended objects from a unified geometric point of view requires an enlargement of superspace. To this aim we study in a systematic way how… Expand

Generating Lie and gauge free differential (super)algebras by expanding Maurer–Cartan forms and Chern–Simons supergravity

J. A. Azcárraga, J. M. Izquierdo, M. Picon, O. Varela
Physics, Mathematics
31 December 2002

Abstract We study how to generate new Lie algebras G (N 0 ,…,N p ,…,N n ) from a given one G . The (order by order) method consists in expanding its Maurer–Cartan one-forms in powers of a real… Expand

BPS states in M theory and twistorial constituents.

I. Bandos, J. A. de Azcárraga, J. M. Izquierdo, J. Lukierski
Physics, Medicine
Physical review letters
17 January 2001

We provide a complete algebraic description of Bogomol'nyi-Prasad-Sommerfield (BPS) states in M theory in terms of primary constituents that we call BPS preons. We argue that any BPS state preserving… Expand

Supertwistors, massive superparticles and κ-symmetry

J. A. Azcárraga, J. M. Izquierdo, J. Lukierski
Physics, Mathematics
15 August 2008

We consider a D = 4 two-twistor lagrangian for a massive particle that incorporates the mass-shell condition in an algebraic way, and extend it to a two-supertwistor model with N = 2 supersymmetry… Expand
