这项工作确定了K(1)-局域自旋玻色谱的E∞结构,方法是将其乘性分裂为E∞胞格。分裂导致Conner A-映射的细胞分解,并产生新的ˆ-Floyd型同构。介绍和说明结果。关于自旋边界的最重要的结果之一可以追溯到Anderson,Brown和Peterson(ABP)。他们证明了当且仅当所有Stiefel-Whitney和KO特征数重合时,两个自旋流形是自旋有界的。此外,可以从附加的2局域分裂mspin∼=计算自旋玻色群。
The work determines the E∞ structure of the K(1)-local spin bordism spectrum by giving a multiplicative splitting into E∞ cells. The splitting leads to a cellular decomposition of the ˆ A-map and creates new isomorphisms of Conner-Floyd type. Introduction and statement of results. One of the most important results on spin bordism goes back to Anderson, Brown and Peterson (ABP). They showed that two spin manifolds are spin bordant if and only if all Stiefel-Whitney and KO-characteristic numbers coincide. Moreover, the spin bordism groups can be computed from the additive 2-local splitting MSpin ∼ =
