容许稳定形式的流形

Manifolds admitting stable forms

Hong-Van Le, Martin Panak, Jiri Vanzura

摘要:

本文给出了$\R^n$上所有稳定形式的直接分类和确定它们的自同构群的方法。我们证明了在6,7,8维上稳定形式与非退化形式是一致的。给出了流形存在稳定形式的必要条件和充分条件。我们还讨论了丰富的性质,这样的流形的几何。

英文摘要:

In this note we give a direct method to classify all stable forms on $\R^n$ as well as to determine their automorphism groups. We show that in dimension 6,7,8 stable forms coincide with non-degnerate forms. We present necessary conditions and sufficient conditions for a manifold to admit a stable form. We also discuss rich properties of the geometry of such manifolds.
