What is the difference between dynamics and kinematics of quantum field theory? I read that in QFT there is no possibility to keep the two things distinct because of a problem with the separability of the Hilbert space on which the theory is defined. So, I would like to know if they are associated to a particular kind of transformation that has to satisfy some constraints.

  • "Dynamics" and "Kinematics" are classical mechanical terms (and are arbitrary even there). It doesn't make much sense to me to try and apply them to quantum theory (field or not). – ACuriousMind Jun 24 '15 at 20:38
