On the Drinfeld Twist for Quantum sl(2)
L. Dabrowski, F. Nesti, P. Siniscalco
Abstract
An isomorphism, up to a twist, between the quasitriangular quantum enveloping algebra Uh(sl(2)) and the (classical) U(sl(2))[[h]]is discussed. The universal twisting element F is given up to the second order in the deformation parameter h.
