Abstract
For a commutative algebra A over denote A module over the smash product is called a jet -module, where is the universal enveloping algebra of In the present paper, we study jet modules in the case of We show that where is the Weyl algebra and L is a Lie subalgebra of called the jet Lie algebra corresponding to Using a Lie algebra isomorphism where is the subalgebra of vector fields vanishing at the point (1, 0), we show that any irreducible finite dimensional L-module is isomorphic to an irreducible -module. As an application, we give tensor product realizations of irreducible jet modules over with uniformly bounded weight spaces.

S 1×C上向量场李代数的不可约射流模块
摘要
对于交换代数A over 表示 粉碎产品上的模块 被称为喷气机 -模块,在哪里 是...的通用包络代数 在本文中,我们研究了在以下情况下的喷射模块 我们证明 哪里 是魏尔代数 并且L是的李子代数 称为对应的射流李代数 使用李代数同构 哪里 是在(1,0)点消失的矢量场的子代数,我们证明了任何不可约的有限维L-模都是不可约的同构-模块。作为应用程序,我们给出了不可约射流模块的张量积实现 具有均匀界定的权重空间。
