The complete set of eigenstates of the Universal R-matrix are constructed and corresponding eigenvalues are calculated.32 pages, LaTeX, no figuresMathematical PhysicsQuantum AlgebraEigenvalues and eigenstates of the s ell_q(2)-invariant Universal R-operator defined for cyclic representations at roots of unitytext
