DRINFELD TWIST FOR TWO-PARAMETRIC DEFORMATION OF gl(2) AND sl(1/2)
نویسنده
چکیده
Drinfeld twist is applied to the Lie algebra gl(2) so that a two-parametric deformation of it is obtained, which is identical to the Jordanian deformation of the gl(2) obtained by Aneva et al. The same twist element is applied to deform the Lie superalgebra sl(1/2), since the gl(2) is embedded into the sl(1/2). By making use of the FRT-formalism, we construct a deformation of the Lie supergroup SL(1/2). Presented at the 7th International Colloquium ”Quantum Groups and Integrable Systems”, Prague, 18–20 June 1998.

The Gervais-Neveu-Felder equation for the Jordanian quasi-Hopf Uh;y(sl(2)) algebra
Using a contraction procedure, we construct a twist operator that satisfies a shifted cocycle condition, and leads to the Jordanian quasi-Hopf Uh;y(sl(2)) algebra. The corresponding universal Rh(y) matrix obeys a Gervais-Neveu-Felder equation associated with the Uh;y(sl(2)) algebra. For a class of representations, the dynamical Yang-Baxter equation may be expressed as a compatibility condition ...
متن کاملDeformed Traces and Covariant Quantum Algebras for Quantum Groups
The q-deformed traces and orbits for the two parametric quantum groups GLqp(2) and GLqp(1|1) are defined. They are subsequently used in the construction of q-orbit invariants for these groups. General qp-(super)oscillator commutation relations are obtained which remain invariant under the co-actions of groups GLqp(2) and GLqp(1|1). The GLqp(2)-covariant deformed algebra is deduced in terms of t...

A two-parametric deformation of U [sl(2)], its representations and complex " spin " Abstract A two-parametric deformation of U [sl(2)] and its representations are considered. This newly introduced two-parametric quantum group denoted as U pq [sl(2)] admits a class of infinite-dimensional representations which have no classical (non-deformed) and one-parametric deformation analogues, even at gen...
متن کامل3 Some deformations of U [ sl ( 2 ) ] and their representations
Some one-and two-parametric deformations of U[sl(2)] and their representations are considered. Interestingly, a newly introduced two-parametric deformation admits a class of infinite-dimensional representations which have no classical (non-deformed) and one-parametric deformation analogues, even at generic deformation parameters.

Non Standard (or Jordanian) deformations of Lie groups and Lie algebras has been a subject of considerable interest in the mathematical physics community. Jordanian deformations for GL(2) were introduced in [1,2], its two parametric generalisation given in [3] and extended to the supersymmetric case in [4]. Non Standard deformations of sl(2) (i.e. at the algebra level) were first proposed in [5...
