comment what kind of system respects $SU(N)$ symmetry?
@Qmechanic i am not sure which question you think is a list question. If the first one, "a N-degenerate system respects $SU(N)$ symmetry?", just a Yes or or No question.

revised Huge confusion with Fermions and Bosons and how they relate to total spin of atom
the writer actually want to say "neutron" other than "fermions", a typo.

comment What's the relation or difference between Lippmann-Schwinger equation and Dyson equation?
To make it clear, allow me to ask alternative questions: do you mean that the generalization of LS equation for many-body problem is not equivalent to Dyson equation? But they are both correct and precise? Could Dyson equation for two-body system with interaction be reduced to LS equation for two-body case?

According to wikipedia, Lippmann-Schwinger equation still could be used for other few-body problem, say for there-body. Maybe for many-body problem it is very difficult to be applied. For the late approach: QFT could describe both interacting few-body and many-body problem, right? If so, the Dyson equation in QFT frame, still could be applied. The difference, i think, is in bare propagator for any Feynman diagram, right?
