Drinfeld twist for quantum su(2) in the adjoint representation
Abstract
We give a detailed description of the adjoint representation of Drinfeld's twist element, as well as of its coproduct, for
s
u
q
(2)
. We also discuss, as applications, the computation of the universal R-matrix in this representation and the problem of symmetrization of identical-particle states with quantum
su(2)
symmetry.
