Differential forms and k-Minkowski spacetime from extended twist
Tajron Jurić, Stjepan Meljanac, Rina Štrajn
We analyze bicovariant differential calculus on -Minkowski spacetime. It is shown that corresponding Lorentz generators and noncommutative coordinates compatible with bicovarian…

Differential algebras on kappa-Minkowski space and action of the Lorentz algebra
Stjepan Meljanac, Sasa Kresic-Juric, Rina Strajn
We propose two families of differential algebras of classical dimension on kappa-Minkowski space. The algebras are constructed using realizations of the generators as formal power…
