Multiparameter quantum Minkowski spacetime and quantum Maxwell equations hierarchy
Earlier we have proposed new qMaxwell equations which are the first members of an infinite new hierarchy of qdifference equations. We have used an indexless formulation in which all indices are traded for two conjugate variables, z,{\bar z}. We proposed also new qMinkowski coordinates which together with z,{\bar z} can be interpreted as the six local coordinates of a SU_q(2,2) flag manifold. In the present paper we generalise the main ingredients of this construction to the multiparameter case using the sevenparameter quantum group deformation of GL(4) and U(gl(4)) and the fourparameter quantum group deformation of SL(4) and U(sl(4)). The main result is the explicit presentation of the multiparameter quantum Minkowski spacetime within the corresponding deformed flag manifold.
