A short introduction to $\kappa$-deformation

Understand

In this short review we describe some aspects of $\kappa$-deformation.

• After discussing the algebraic and geometric approaches to $\kappa$-Poincar\'e algebra we construct the free scalar field theory, both on non-commutative $\kappa$-Minkowski space and on curved momentum space.
• Finally, we make a few remarks concerning interacting scalar field.
