Contractions of 3-dimensional representations of the Lie algebra \(\mathfrak{sl}(2)\). (English) Zbl 1254.17026
The authors write down the \(\mathbb Z_3\)-graded contractions of the 3-dimensional irreducible representation of \(\mathfrak{sl}(2)\) without identifying or discussing the result.
Reviewer’s remark: This material is old, and the calculation trivial. I do not understand how such a paper can slip by a referee. Already the second sentence of the abstract “In this theory, grading of the given Lie algebra is characterized by two sets of parameters satisfying a derived set of equations” should alarm every reader.
