Please teach me this problem:
It seem that following Haag's theorem there not exist quantized equation of motion for interacting fields.So I don't understand how to know the form of interacting Lagrangian has form of product of fields(example Lagrangian of Fermi field interacting with electromagnetic field).
Thank you very much for advance.
