Resumen:
|
We prove that the missing label operators for the state labelling problem in the Wigner supermultiplet model su(2)×su(2) ? su(4) can be solved naturally without explicitly using enveloping algebras. Considering a contraction of Lie algebras naturally associated to the reduction chain su(2)×su(2) ,! su(4), we recover the Moshinsky-Nagel operators as functions of the Casimir operators of su(4), the spin-isospin subalgebra and the corresponding inhomogeneous contraction
