在Kervaire-Milnor和Hill-Hopkins-Ravenel工作的基础上,Wang和Xu证明了唯一具有独特可微结构的奇数维n是1、3、5和61。我们证明了在140以下具有唯一可微结构的偶数维只有2,6,12,56,也许还有4。
Building off of the work of Kervaire–Milnor and Hill–Hopkins–Ravenel, Wang and Xu showed that the only odd dimensions n for which Sn has a unique differentiable structure are 1, 3, 5, and 61. We show that the only even dimensions below 140 for which Sn has a unique differentiable structure are 2, 6, 12, 56, and perhaps 4.
