Sažetak
In this contribution we review the method to obtain information about the classical dynamics of a higher spin field by minimally coupling the field via a conserved current to a simple free fermion, and by integrating out the latter. We consider here the two point correlators of two conserved currents, which allow us to determine the effective action to quadratic order. We show that this gives rise to the classical equation of motion of the Fronsdal type. We point out the importance of the contributions of the tadpole and seagull terms and the ambiguity related to the choice of the conserved currents.
