The generators *(J_{\pm}, J_0)* of the algebra *U_q(sl(2))* is our starting point. An invertible nonlinear map involving, apart from q, a second arbitrary complex parameter h, defines a triplet *({\hat X},{\hat Y},{\hat H})*. The latter set forms a closed algebra under commutation relations. The nonlinear algebra *U_{q,h}(sl(2))*, thus generated, has... Show more
