BICOVARIANT CALCULUS ON TWISTED <font>ISO</font>(N), QUANTUM POINCARÉ GROUP AND QUANTUM MINKOWSKI SPACE
A bicovariant calculus on the twisted inhomogeneous multiparametric $q$-groups of the $B_n,C_n,D_n$ type, and on the corresponding quantum planes, is found by means of a projection from the bicovariant calculus on $B_{n+1}$, $C_{n+1}$, $D_{n+1}$. In particular we obtain the bicovariant calculus on a dilatation-free $q$-Poincar\'e group $ISO_q (3,1)$, and on …
