Filtered Lie conformal algebras whose associated graded algebras are isomorphic to that of general conformal algebra
Yucai Su, Xiaoqing Yue
Let be a filtered Lie conformal algebra whose associated graded conformal algebra is isomorphic to that of general conformal algebra . In this paper, we prove that $G\con…
Poisson algebras, Weyl algebras and Jacobi pairs
Yucai Su
We study Jacobi pairs in details and obtained some properties. We also study the natural Poisson algebra structure $(\PP,[...,...],...)$ on the space $\PP:=\C[y]((x^{-\frac1N}))$ f…
Indecomposable modules of the intermediate series over W(a,b) algebras
Yucai Su, Ying Xu, Xiaoqing Yue
For any complex parameters a,b, the W(a,b) algebra is the Lie algebra with basis {L_i,W_i|i\in Z}, and relations [L_i,L_j]=(j-i)L_{i+j}, [L_i,W_j]=(a+j+bi)W_{i+j},[W_i,W_j]=0. In t…
Quasifinite representations of a class of Block type Lie algebras $\BB$
Yucai Su, Chunguang Xia, Ying Xu
Intrigued by a well-known theorem of Mathieu's on Harish-Chandra modules over the Virasoro algebra, we give an analogous result for a class of Block type Lie algebras $\BB$, where…
