A gage-invariant Lagrangian for a Poincare group

A previously proposed method is used to analyze the possibility of building a gage-invariant action for a Poincare group which satisfies the physical requirements. It is shown that such an action cannot be built in the case of precise symmetry, but can be built with spontaneous disruption of symmetry. In this case the possibility arises of the existence of massive vector particles which correspond to the gage fields of the translation subgroup.
