正曲率的几何形式齐次度量
Geometrically formal homogeneous metrics of positive curvature
摘要：
一个黎曼流形称为几何形式的，如果调和形式的楔积又是调和的，这意味着在紧的情况下，流形在有理同伦理论的意义下是拓扑形式的。本文证明了一个具有正截面曲率的黎曼度量的流形是拓扑形式的。尽管如此，我们表明，在齐次黎曼度量的正截面曲率的几何形式的度量是对称的，或一个度量的理性的同源领域。
英文摘要：
A Riemannian manifold is called geometrically formal if the wedge product of harmonic forms is again harmonic, which implies in the compact case that the manifold is topologically formal in the sense of rational homotopy theory. A manifold admitting a Riemannian metric of positive sectional curvature is conjectured to be topologically formal. Nonetheless, we show that among the homogeneous Riemannian metrics of positive sectional curvature a geometrically formal metric is either symmetric, or a metric on a rational homology sphere.
