Kivonat:

The Rarita-Schwinger equation coupled to an external electromagnetic field 
exhibits acausal propagation properties. This is the Velo-Zwanziger 
phenomenon and was considered as an undesirable and unphysical feature. In 
this talk I analyse the Rarita-Schwinger equation in a curved background 
and an external electromagnetic field. I derive an equivalent system of 
hyperbolic evolution equations together with constraints which is 
equivalent to the Rarita-Schwinger equation. I describe the emergence of 
the Velo-Zwanziger phenomenon in terms of the propagation of constraints.
