Sazetak:
We unify k-Poincare algebra and k-Minkowski spacetime by embeding them
into quantum phase space. The quantum phase space has Hopf algebroid
structure to which we apply the twist in order to get k-deformed Hopf
algebroid structure and k-deformed phase space. We explicitly construct
k-Poincare-Hopf algebra and k-Minkowski spacetime from twist. It is
outlined how this construction can be extended to k-deformed super algebra
including exterior derivative and forms. Our results are relevant for
constructing physical theories on noncommutative spacetime by twisting Hopf
algebroid phase space structure.
