Recently, a class of transformations of *R_q*-matrices was introduced such that the *q \to 1* limit gives explicit nonstandard *R_h*-matrices. The transformation matrix is singular as *q \to 1*. For the transformed matrix, the singularities, however, cancel yielding a well-defined construction. We have shown that our method can be implemented... Show more
