Speciální teorie relativity a modifikace

In 2000 G. Amelino-Camelia came up with a new suggestion how to modify the special theory of relativity to agree with some possible conclusions of quantum gravity at high energies. Since then, many publications appeared which are dealing with concrete suggestions of such a theory. These theories differ in construction, so they have different consequences that do not occur in the special theory of relativity. In this thesis I am dealing with fundamental properties of theories like Canonical DSR, Gravity's rainbow or the Theory of relative locality.
