Abstract

A two-parametric generalization of the Jordanian deformation Uh(sl(2))U_h (sl(2)) of sl(2)sl(2) is presented. This involves Jacobian elliptic functions. In our deformation U(h,k)(sl(2))U_{(h,k)}(sl(2)), for k2=1k^2=1 one gets back Uh(sl(2))U_h(sl(2)). The constuction is presented via a nonlinear map on sl(2)sl(2). This invertible map directly furnishes the highest weight irreducible representations of U(h,k)(sl(2))U_{(h,k)}(sl(2)). This map also provides two distinct induced Hopf stuctures, which are exhibited. One is induced by the classical sl(2)sl(2) and the other by the distinct one of Uh(sl(2))U_h(sl(2)). Automorphisms related to the two periods of the elliptic functions involved are constructed. Translations of one generator by half and quarter periods lead to interesting results in this context. Possibilities of applications are discussed briefly.
