论文摘要
我描述了目前以$ d \ geq 5 $的闻名，关于与其边界相对于$ d $ disc的差异性的合理同型类型，以及与$ d $ d $ d $ d $ d $ d $ d $ d的欧几里得空间密切相关的同构同构的群体。
I describe what is currently known, for $d \geq 5$, about the rational homotopy type of the group of diffeomorphisms of the $d$-disc relative to its boundary, and the closely related group of homeomorphisms of $d$-dimensional Euclidean space.
