Abstract
The generators of the algebra sℓξ(2), which result from the nonstandard (Jordanian) deformation of the algebra sℓ(2), are realized in the form of finite-difference operators acting in a function space. This allows realizing arbitrary-dimensional representations of sℓξ(2) in the polynomial space that are in one-to-one correspondence with usual matrices of an appropriate dimension. We discuss using the suggested realization to construct and investigate the universal R-matrix invariant with respect to the action of the algebra sℓξ(2).
