本文给出了(W(α,β)的泛中心扩张)上所有不可约Harish-Chandra模的分类,其中ai = 0,B i 1,i = 1,2.此外,还得到了有限维权空间的不可约权模的分类,其中ai = 0,− 1 ≤ B i 1,如果B i ∈ N,i = 1,2.最后,我们研究了的子代数上Verma模的不可约性。
In this article, classification of all irreducible Harish–Chandra modules over (the universal central extension of W(α, β)) for a i = 0, b i ≠ 1, i = 1, 2 is given. In addition, classification of irreducible weight modules with a finite dimensional weight space over for a i = 0, − 1 ≤ b i ≠ 1 if b i ∈ ℤ, i = 1, 2 is also obtained. Finally, we study the irreducibility of Verma modules over a subalgebra of .
