论文摘要
我们证明,通过展示$ h $ h $ cobordant的歧管,其映射级别的类别具有不同的基础性,映射类组并不是高维流形的$ h $ bobordism。为此,我们引入了“ $ h $ block”捆绑的模量空间,并了解其与普通块束的模量空间的差异。
We prove that the mapping class group is not an $h$-cobordism invariant of high-dimensional manifolds by exhibiting $h$-cobordant manifolds whose mapping class groups have different cardinalities. In order to do so, we introduce a moduli space of "$h$-block" bundles and understand its difference with the moduli space of ordinary block bundles.
