李代数和分次李代数上的微分算子

Differential operators on Lie and graded Lie algebras

G. Sardanashvily

摘要:

结合代数上的微分算子理论没有直接推广到非结合代数上。我们考虑李代数上的微分算子。一个关键点是李代数中的乘法是它的导子。李代数上的高阶微分算子被定义为一阶微分算子的合成。定义了李代数上的Chevalley-Eilenberg微分.有限维李代数,泊松代数,代数的向量场,代数的典型交换关系的例子被认为是。分次李代数上的微分算子的定义与李代数上的微分算子相同。

英文摘要:

Theory of differential operators on associative algebras is not extended to the non-associative ones in a straightforward way. We consider differential operators on Lie algebras. A key point is that multiplication in a Lie algebra is its derivation. Higher order differential operators on a Lie algebra are defined as composition of the first order ones. The Chevalley--Eilenberg differential calculus over a Lie algebra is defined. Examples of finite-dimensional Lie algebras, Poisson algebras, algebras of vector fields, and algebras of canonical commutation relations are considered. Differential operators on graded Lie algebras are defined just as on the Lie ones.
