In this talk, we define the resonances of Dirac operators as poles of the meromorphic continuation of the truncated resolvent and discuss a result about their localization: a kind of Rellich Theorem. Firstly, we consider the case of the free Dirac operator perturbated by a bounded and compactly supported external field. Secondly, we consider the case of the MIT bag model outside a smooth and bounded obstacle.
