标准拉普拉斯算子

The Standard Laplace Operator

Uwe Semmelmann, Gregor Weingart

摘要:

标准拉普拉斯算子是霍奇拉普拉斯算子在微分形式上对任意几何向量丛的推广,或者它可以被看作是卡西米尔算子作用在对称空间上的齐次向量丛的截面上对一般黎曼流形的推广。强调函方面的标准拉普拉斯算子$Δ$的几何向量丛的范畴,我们表明,标准拉普拉斯算子交换不仅与所有的同态,但也与一大类自然的一阶微分算子之间的几何向量丛。文中还列举了几个例子来说明本文的结论。

英文摘要:

The standard Laplace operator is a generalization of the Hodge Laplace operator on differential forms to arbitrary geometric vector bundles, alternatively it can be seen as generalization of the Casimir operator acting on sections of homogeneous vector bundles over symmetric spaces to general Riemannian manifolds. Stressing the functorial aspects of the standard Laplace operator $Δ$ with respect to the category of geometric vector bundles we show that the standard Laplace operator commutes not only with all homomorphisms, but also with a large class of natural first order differential operators between geometric vector bundles. Several examples are included to highlight the conclusions of this article.
