Vector Supersymmetry: Casimir operators and contraction from OSp(3,2|2)
Roberto Casalbuoni, Federico Elmetti, Joaquim Gomis +3
We study some algebraic properties of the 'vector supersymmetry' (VSUSY) algebra, a graded extension of the four-dimensional Poincare' algebra with two odd generators, a vector and…
Infinite Sequence of Poincare Group Extensions: Structure and Dynamics
Sotirios Bonanos, Joaquim Gomis
We study the structure and dynamics of the infinite sequence of extensions of the Poincar{é} algebra whose method of construction was described in a previous paper [1]. We give exp…
A note on the Chevalley-Eilenberg Cohomology for the Galilei and Poincare Algebras
Sotirios Bonanos, Joaquim Gomis
We construct in a systematic way the complete Chevalley-Eilenberg cohomology at form degree two, three and four for the Galilei and Poincare groups. The corresponding non-trivial f…
Enlarged NH symmetries: Particle Dynamics and Gauge Symmetries
Joaquim Gomis, Jerzy Lukierski
We show how the Newton-Hooke (NH) symmetries, representing a nonrelativistic version of de-Sitter symmetries, can be enlarged by a pair of translation vectors describing in Galilea…
