On the Casimir Elements of q-Algebras U'_q(so_n) and Their Eigenvalues in Representations
arXiv:math/9911201
Abstract
The nonstandard q-deformed algebras U'_q(so_n) are known to possess q-analogues of Gel'fand-Tsetlin type representations. For these q-algebras, all the Casimir elements (corresponding to basis set of Casimir elements of so(n)) are found, and their eigenvalues within irreducible representations are given explicitly.
