Title Extended D=3 Bargmann supergravity from a Lie algebra expansion Type Journal Article
Year 2019 Publication Nuclear Physics B Abbreviated Journal Nucl. Phys. B
Volume 946 Issue Pages 114706 - 14pp
Keywords
Abstract In this paper we show how the method of Lie algebra expansions may be used to obtain, in a simple way, both the extended Bargmann Lie superalgebra and the Chern-Simons action associated to it in three dimensions, starting from D = 3, N = 2 superPoincare and its corresponding Chern-Simons supergravity.

Title Minimal D=4 supergravity from the superMaxwell algebra Type Journal Article
Year 2014 Publication Nuclear Physics B Abbreviated Journal Nucl. Phys. B
Volume 885 Issue Pages 34-45
Keywords
Abstract We show that the first-order D = 4, N = 1 pure supergravity lagrangian four-form can be obtained geometrically as a quadratic expression in the curvatures of the Maxwell superalgebra. This is achieved by noticing that the relative coefficient between the two terms of the lagrangian that makes the action locally supersymmetric also determines trivial field equations for the gauge fields associated with the extra generators of the Maxwell superalgebra. Along the way, a convenient geometric procedure to check the local supersymmetry of a class of lagrangians is developed.

Title D=3 (p, q)-Poincare supergravities from Lie algebra expansions Type Journal Article
Year 2012 Publication Nuclear Physics B Abbreviated Journal Nucl. Phys. B
Volume 854 Issue 1 Pages 276-291
Keywords
Abstract We use the expansion of superalgebras procedure (summarized in the text) to derive Chem-Simons (CS) actions for the (p, q)-Poincare supergravities in three-dimensional spacetimes. After deriving the action for the (p, 0)-Poincare supergravity as a CS theory for the expansion osp(p vertical bar 2: R)(2, 1) of osp(p vertical bar 2: R), we find the general (p, q)-Poincare superalgebras and their associated D = 3 supergravity actions as CS gauge theories from an expansion of the simple osp(p + q vertical bar 2, R) superalgebras, namely osp(p + q vertical bar 2, R)(2, 1, 2).

Title On a class of n-Leibniz deformations of the simple Filippov algebras Type Journal Article
Year 2011 Publication Journal of Mathematical Physics Abbreviated Journal J. Math. Phys.
Volume 52 Issue 2 Pages 023521 - 13pp
Keywords
Abstract We study the problem of infinitesimal deformations of all real, simple, finite-dimensional Filippov (or n-Lie) algebras, considered as a class of n-Leibniz algebras characterized by having an n-bracket skewsymmetric in its n-1 first arguments. We prove that all n > 3 simple finite-dimensional Filippov algebras (FAs) are rigid as n-Leibniz algebras of this class. This rigidity also holds for the Leibniz deformations of the semisimple n = 2 Filippov (i.e., Lie) algebras. The n = 3 simple FAs, however, admit a nontrivial one-parameter infinitesimal 3-Leibniz algebra deformation. We also show that the n >= 3 simple Filippov algebras do not admit nontrivial central extensions as n-Leibniz algebras of the above class.

Title Contractions of Filippov algebras Type Journal Article
Year 2011 Publication Journal of Mathematical Physics Abbreviated Journal J. Math. Phys.
Volume 52 Issue 1 Pages 013516 - 24pp
Keywords
Abstract We introduce in this paper the contractions B-c of n-Lie (or Filippov) algebras B and show that they have a semidirect structure as their n = 2 Lie algebra counterparts. As an example, we compute the nontrivial contractions of the simple A(n+1) Filippov algebras. By using the. Inonu-Wigner and the generalized Weimar-Woods contractions of ordinary Lie algebras, we compare (in the B = A(n+1) simple case) the Lie algebras Lie B-c (the Lie algebra of inner endomorphisms of B-c) with certain contractions (Lie B)(IW) and (Lie B)(W-W) of the Lie algebra Lie B associated with B.
