SYMMETRIC MULTIPLETS IN QUANTUM ALGEBRAS
SYMMETRIC MULTIPLETS IN QUANTUM ALGEBRAS
We consider a modified version of the coproduct for [Formula: see text] and show that in the limit q→1, there exists an essentially non-cocommutative coproduct. We study the implications of this non-cocommutativity for a system of two spin-1/2 particles. Here it is shown that, unlike the usual case, this nontrivial …
