q -deformed Lorentz-algebra in Minkowski phase space
The European Physical Journal C - Particles and Fields(1999)
摘要
. In the present paper we show that the Lorentz algebra L as defined in [5] is isomorphic to an algebra Û closely related to a q -deformed SU_q(2) ⊗ SU_q(2) algebra. On this algebra Û we define a Hopf algebra structure and show its action on q -spinor modules. This algebra is related to the q -deformed Minkowski space algebra by a non invertible factorisation.
