摘要：

Recently, an infinite family of chiral Virasoro vertex operators, whose exchange algebra is given by the universal R-matrix of SL(2)q, has been constructed. In the present paper, the case of non-linearly (W-) extended Virasoro symmetries, related to the algebras A(N), N > 1, is considered along the same line. Contrary to the previous case (A1) the standard R-matrix of SL(N + 1)q does not come out, and a different solution of Yang and Baxter's equations is derived. The associated quantum group structure is displayed.
