Abstract

In this paper we propose algebraic universal procedure for deriving "fusion rules" and Baxter equation for any integrable model with Uq(sl2) symmetry of Quantum Inverse Scattering Method. Universal Baxter Q- operator is got from the certain infinite dimensional representation called q-oscillator one of the Universal R- matrix for Uq(sl2) affine algebra (first proposed by V. Bazhanov, S.Lukyanov and A.Zamolodchikov for quantum KdV case). We also examine the algebraic properties of Q-operator.
