Translational symmetries of quadratic lagrangians
Andrea Barducci, Roberto Casalbuoni
In this paper we show that a quadratic lagrangian, with no constraints, containing ordinary time derivatives up to the order of dynamical variables, has symmetries co…
A particle model with extra dimensions from Coadjoint Poincare' Symmetry
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
Starting from the coadjoint Poincaré algebra we construct a point particle relativistic model with an interpretation in terms of extra-dimensional variables. The starting coadjoint…
Non-relativistic -contractions of the Coadjoint Poincaré algebra
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
We study a class of extensions of the k-contracted Poincaré algebra under the hipotesis of generalizing the Bargmann algebra and his central charge. As we will see this type of con…
Contractions of the Maxwell algebra
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
We construct all the possible non-relativistic, non-trivial, Galilei and Carroll k-contractions also known as k-1 p-brane contractions of the Maxwell algebra in space-time di…
VSUSY models with Carroll or Galilei invariance
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
The general method introduced in a previous paperto build up a class of models invariant under generalization of Carroll and Galilei algebra is extended to systems including a set…
Confined dynamical systems with Carroll or Galilei symmetries
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
We introduce a general method to construct classes of dynamical systems invariant under generalizations of the Carroll and of the Galilei groups. The method consists in starting fr…
