Wigner's classification: "The identification of particle species with irreducible unitary representations of the symmetry group acting on matter fields over spacetime."

this sounds interesting ngl

"Physically, one is interested in irreducible projective unitary representations of the Poincaré group. After all, two vectors in the quantum Hilbert space that differ by multiplication by a constant represent the same physical state"
