Sazetak:

The first part of my talk will be based on arXiv:1112.2426, (under
publication), in which I introduced in a Lorentz-covariant way the basic
tools of differential geometry in kappa-Minkowski noncommutative spacetime.
As an application, I will show the analysis of symmetries and conserved
quantities of a complex scalar field. The tools I introduced will be useful,
I believe, in constructing more interesting field theories in a covariant
way, e.g. gauge theories. The second part of my talk will be based on
PhysRevD.86.084032 with J. Carmona and J. Cortes. In this work we considered
from a phenomenological point of view generic deformations of the
kinematical structure of special relativity, of which the kappa-Poincaré
group is an example. We studies, at first order in the deformation energy
scale, the sufficient conditions in order to retain the equivalence between
inertial observers. The deformation dictated by the kappa-Poincaré group,
for example, satisfy these conditions.
