QuantumR-matrix and intertwiners for the Kashiwara algebra

We study the algebraB _q (g) presented by Kashiwara and introduce intertwiners similar toq-vertex operators. We show that a matrix determined by 2-point functions of the intertwiners coincides with a quantumR-matrix (up to a diagonal matrix) and give the commutation relations of the intertwiners. We also introduce an analogue of the universalR-matrix for the Kashiwara algebra.
