Abstract:
We study representations of the non-standard quantum deformation $Uโ_q\mathfrak {so}_n$ of $U\mathfrak {so}_n$ via a Verma module approach. This is used to recover the classification of finite-dimensional modules for $q$ not a root of unity, given by classical and non-classical series. We obtain new results at roots of unity, including the classification of self-adjoint representations on Hilbert spaces.References
