一维嵌入复形

A one-dimensional embedding complex

Kevin P. Scannell, Dev P. Sinha

摘要:

给出了欧几里得空间中“长纽结”空间的有理同伦群的第一个显式计算。我们定义了一个谱序列,它收敛于这些有理同伦群,这些同伦群的E^1项是用辫李代数定义的。对于奇数k,我们建立了这个谱序列的消失线,证明了这个E^1项的行的欧拉示性数为零,并在有限范围内计算了E^2。

英文摘要:

We give the first explicit computations of rational homotopy groups of spaces of "long knots" in Euclidean spaces. We define a spectral sequence which converges to these rational homotopy groups whose E^1 term is defined in terms of braid Lie algebras. For odd k we establish a vanishing line for this spectral sequence, show the Euler characteristic of the rows of this E^1 term is zero, and make calculations of E^2 in a finite range.
