Sažetak
We deform Heisenberg algebra and corresponding coalgebra by twist. We present undeformed and deformed tensor identities. Coalgebras for the generalized Poincar\'{; ; ; e}; ; ; algebras have been constructed. The exact universal $R$-matrix for the deformed Heisenberg (co)algebra is found. We show, up to the third order in the deformation parameter, that in the case of $\kappa$-Poincar\'{; ; ; e}; ; ; Hopf algebra this $R$-matrix can be expressed in terms of Poincar\'{; ; ; e}; ; ; generators only. This implies that the states of any number of identical particles can be defined in a $\kappa$-covariant way.
