From the mathematical point of view this deformation is rather quantum-braided group. Global and local structure of this quantum-braided Poincaré group is investigated. A kind of ``quantum metrics'' is introduced in the $q$-Minkowski space.LaTeX (A4), 11pp., KFT UL 7/93High Energy Physics - Theorytext
