不变微分对

Invariant Differential Pairings

Jens Kroeske

摘要:

本文引入了M阶不变双线性微分对的概念,并给出了其形式定义。如果流形具有AHS结构,则构造各种一阶对。这就给出了具有AHS结构的齐性空间上除某些完全退化情形外的所有一阶不变双线性微分对的分类。在此齐性空间上构造了高阶不变双线性微分对,从而对非退化情形下的复射影空间进行了分类。退化的情况对应于存在不变的线性微分算子。

英文摘要:

In this paper the notion of an M-th order invariant bilinear differential pairing is introduced and a formal definition is given. If the manifold has an AHS structure, then various first order pairings are constructed. This yields a classification of all first order invariant bilinear differential pairings on homogeneous spaces with an AHS structure except for certain totally degenerate cases. Moreover higher order invariant bilinear differential pairings are constructed on these homogeneous spaces which leads to a classification on complex projective space for the non degenerate cases. A degenerate case corresponds to the existence of an invariant linear differential operator.
