论文摘要
我们确定$π_*（bdiff_ \ partial（d^{2n}）））\ otimes \ mathbb {q} $，对于$ 2N \ geq 6 $，完全以$* \ leq 4n-10 $为单位，远远超出了伪造稳定范围。此外，在这些同型组中，我们发现了一个系统的结构：我们在某些“频段”程度之外确定它们。
We determine $π_*(BDiff_\partial(D^{2n})) \otimes \mathbb{Q}$ for $2n \geq 6$ completely in degrees $* \leq 4n-10$, far beyond the pseudoisotopy stable range. Furthermore, above these degrees we discover a systematic structure in these homotopy groups: we determine them outside of certain "bands" of degrees.
