Covariant formulation of Noether's Theorem for translations on kappa-Minkowski spacetime
Alessandra Agostini
The problem of finding a formulation of Noether's theorem in noncommutative geometry is very important in order to obtain conserved currents and charges for particles in noncommuta…
Generalizing the Noether theorem for Hopf-algebra spacetime symmetries
Alessandra Agostini, Giovanni Amelino-Camelia, Michele Arzano +2
Over these past few years several quantum-gravity research groups have been exploring the possibility that in some Planck-scale nonclassical descriptions of spacetime one or anothe…
kappa-Minkowski representations on Hilbert spaces
Alessandra Agostini
The algebra of functions on kappa-Minkowski noncommutative spacetime is studied as algebra of operators on Hilbert spaces. The representations of this algebra are constructed and c…
Action functional for kappa-Minkowski Noncommutative Spacetime
Alessandra Agostini, Giovanni Amelino-Camelia, Michele Arzano +1
We examine some alternative possibilities for an action functional for -Minkowski noncommutative spacetime, with an approach which should be applicable to other spacetimes with…
Fields and symmetries in -Minkowski noncommutative spacetime
Alessandra Agostini
We have investigated some issues relevant for the possibility to construct physical theories on the -Minkowski noncommutative spacetime. The notion of field in -Minkowski has…
Hopf-algebra description of noncommutative-spacetime symmetries
Alessandra Agostini
I give a brief summary of the results reported in hep-th 0306013 in collaboration with G. Amelino-Camelia and F. D'Andrea. I focus on the analysis of the symmetries of -Minkowsk…
Hopf-algebra description of noncommutative-spacetime symmetries
Alessandra Agostini, Giovanni Amelino-Camelia, Francesco D'Andrea
In the study of certain noncommutative versions of Minkowski spacetime there is still a large ambiguity concerning the characterization of their symmetries. Adopting as our case st…
Generalized Weyl systems and kappa-Minkowski space
Alessandra Agostini, Fedele Lizzi, Alessandro Zampini
We introduce the notion of generalized Weyl system, and use it to define *-products which generalize the commutation relations of Lie algebras. In particular we study in a comparat…
