在本文中,我们研究正弯曲 Bazaikin 空间的拓扑。我们证明,唯一与齐次空间同伦等价的 Bazaikin 空间是 Berger 空间。此外,我们计算它们的 Pontryagin 类和链接形式,得出这样的结论:不存在同胚的正弯曲 Bazaikin 空间对,至少当具有整数系数的第六上同调群的阶数小于 10 时
In this note we study the topology of the positively curved Bazaikin spaces. We show that the only Bazaikin space that is homotopically equivalent to a homogeneous space is the Berger space. Moreover, we compute their Pontryagin classes and linking form to conclude that there is no pair of positively curved Bazaikin spaces which are homeomorphic, at least if the order of the sixth cohomology group with integer coefficients is less than 10
