## Main Question or Discussion Point

Hi.

I am interested in finding books dealing with symmetries.

Specifically books that make me understand assertions like, and I quote Orodruin's #10 and #16 here https://www.physicsforums.com/threa...leaves-the-given-lagrangian-invariant.984601/, 'a rotation in the CoM frame is equivalent to rotation+translation in the original one' or 'boosts and rotations do not commute'.

Besides, and I quote Tong's QFT lecture notes, 'The role of symmetries in field theory is possibly even more important than in particle mechanics. There are Lorentz symmetries, internal symmetries, gauge symmetries, supersymmetries....'

Thus I am also interested in books dealing with symmetries in a QFT context.

What are your suggestions?

Thank you.
