黎曼流形上的共形Killing形式

Conformal Killing forms on Riemannian manifolds

U. Semmelmann

摘要:

共形Killing形式是黎曼流形上共形向量场的自然推广。它们被定义为共形不变的一阶微分算子的核中的部分。本文证明了近Kaehler流形和弱G_2流形上共形Killing型的存在性。此外,我们给出了特殊的共形Killing形式的完整描述。进一步的结果是一个尖锐的上界的尺寸空间的共形Killing形式。

英文摘要:

Conformal Killing forms are a natural generalization of conformal vector fields on Riemannian manifolds. They are defined as sections in the kernel of a conformally invariant first order differential operator. We show the existence of conformal Killing forms on nearly Kaehler and weak G_2-manifolds. Moreover, we give a complete description of special conformal Killing forms. A further result is a sharp upper bound on the dimension of the space of conformal Killing forms.
