Twisting kappa-deformed phase space

We briefly discuss the twisting procedure applied to the $κ$-deformed space-time. It appears that one can consider only two kinds of such twistings: in space and time directions. For both types of twisitngs we introduce related phase spaces and consider briefly their properties. We discuss in detail the changes of duality relations under the action of twist. The Jordanian twisted space-time and phase space in D=2 are also commented.

Twisted Classical Phase Space

We consider relativistic phase space constructed by the twist procedure from the translation sector of the standard, nondeforned Poincare algebra. Using the concept of cross product algebra we derive two kinds of phase space with noncommuting configuration space. The generalized uncertainty relations are formulated.
