We have reformulated the two elliptic algebras U_{q,p}(g) and E_{q,p}(g) as topological algebras over the ring of formal power series in p and shown that they are isomorphic for g=gl_n. We also have formulated the dynamical quantum Z-algebras associated with U_{q,p}(g), and shown that the irreducibility of the U_{q,p}(g)-modules is governed by the corresponding Z-modules. As for the multivariate elliptic hypergeometric functions, we have shown that the sl_n type found by Kajihara-Noumi and Rosengren is given by a certain tensor product of the symmetric fusions of the sl_n type vertex-face intertwining vectors and their duals. Furthermore, as an application of the representations of U_{q,p}(sl_2), we have derived and analyzed the structure factor of the massless XXZ model exactly.

将两个椭圆代数U_{q，p}(g)和E_{q，p}(g)重新表述为p中形式幂级数环上的拓扑代数，并证明了它们在g=gl_n时是同构的。我们还建立了与U_{q，p}(g)相关的动态量子z -代数，并证明了U_{q，p}(g)-模的不可约性是由相应的z -模控制的。对于多元椭圆型超几何函数，我们证明了Kajihara-Noumi和Rosengren发现的sl_n型是由sl_n型顶点面交织向量及其对偶的对称融合的某个张量积给出的。此外，作为U_{q，p}（sl_2）表示的应用，我们准确地推导并分析了无质量XXZ模型的结构因子。
