q-Deformed Orthogonal and Pseudo-Orthogonal Algebras and Their Representations
A. M. Gavrilik, A. U. Klimyk
Abstract
Deformed orthogonal and pseudo-orthogonal Lie algebras are constructed which differ from deformations of Lie algebras in terms of Cartan subalgebra and root vectors and which make it possible to construct representations by operators acting according to Gel'fand--Tsetlin-type formulas. Unitary representations of the q-deformed algebras Uq(son,1) are found.
