摘要:
我们解决了一维几何中希尔伯特第三问题的高维版本,并在更高维度中将该问题归结为群同调中的计算。我们的核心结果涉及Zakharevich的剪刀全等$K$-理论谱,其同伦群是经典剪刀全等群的正确高维版本。我们证明该谱是一个Thom谱,其底空间是Tits复形的同伦轨道空间。相关计算迅速由此更基础的结果得出。
英文摘要:
We solve the higher version of Hilbert's Third Problem for one-dimensional geometries, and in higher dimensions we reduce the problem to a computation in group homology. Our central result concerns the scissors congruence $K$-theory spectrum of Zakharevich, whose homotopy groups are the correct higher version of the classical scissors congruence groups. We prove that this spectrum is a Thom spectrum, whose base space is the homotopy orbit space of a Tits complex. The relevant computations quickly follow from this more foundational result.
