关于嵌入汉明球及其在正曲率中的应用

On Embedding Hamming Spheres with Applications to Positive Curvature

Muhammad Abdullah

AI总结:

该研究针对闭正曲率流形的等距ℤ_p环面作用得到同伦分类,改进了对称秩相关结果,并推广了Wilking的球嵌入构造至任意素数,具有几何领域的独立研究价值。

AI中文摘要:

我们研究闭正曲率流形上的等距ℤ_p环面作用,得到同伦分类结果。这使我们能改进Fang-Rong和Ghazawneh关于3n/8半极大对称秩的结果,该改进见作者与Searle工作中的定理B和推论C。过程中,我们将Wilking的球嵌入构造从二元情形推广到任意素数,得到定理C,这是一项具有独立意义的几何构造。

英文摘要:

We consider isometric $\mathbb{Z}_{p}$-torus actions on closed, positively curved manifolds, obtaining a homotopy classification result. This allows us to strengthen on the improvement of the $3n/8$ half-maximal symmetry rank result of Fang-Rong and Ghazawneh given in Theorem B and Corollary C in the work of the author and Searle. Along the way, we generalize a sphere-embedding construction of Wilking from the binary case to arbitrary primes in Theorem C, which is a geometric construction of independent interest.
