Bicovariant Calculus on Twisted ISO(N), Quantum Poincare' Group and Quantum Minkowski Space
Paolo Aschieri, Leonardo Castellani
Abstract
A bicovariant calculus on the twisted inhomogeneous multiparametric q-groups of the Bn,Cn,Dn type, and on the corresponding quantum planes, is found by means of a projection from the bicovariant calculus on Bn+1, Cn+1, Dn+1. In particular we obtain the bicovariant calculus on a dilatation-free q-Poincaré group ISOq (3,1), and on the corresponding quantum Minkowski space. The classical limit of the Bn,Cn,Dn bicovariant calculus is discussed in detail.
