with the writer who immediately allowed his name to be published, as may be seen by a reference to our columns (May 1911, p. 187). This letter has long been lost, but at the time we stated and we still believe that it contained nothing beyond a statement to the effect that the writer should give his name. This having been done, we did not think it necessary to publish the letter itself, and not...

General Construction of Nonstandard R h - matrices as Contraction Limits of R q - matrices

A class of transformations of Rq-matrices is introduced such that the q → 1 limit gives explicit nonstandard Rh-matrices. The transformation matrix is singular itself at q → 1 limit. For the transformed matrix, the singularities, however, cancel yielding a well-defined construction. Our method can be implemented systematically for R-matrices of all dimensions and not only for sl(2) but also for...
