函数空间中的Whitehead积:Quillen模型公式
Whitehead products in function spaces: Quillen model formulae
摘要:
研究了函数空间的一般分支的有理同伦群中的Whitehead积。对于任意基映射f:X \to Y的分量,在基或自由函数空间中,我们的主要结果直接用f的Quillen极小模型表示Whitehead积.这些结果遵循从一个纯粹的代数发展的设置链复形的微分分次李代数,这是感兴趣的在其本身的权利。我们应用这些结果研究了函数空间分支的Whitehead长度。
英文摘要:
We study Whitehead products in the rational homotopy groups of a general component of a function space. For the component of any based map f: X \to Y, in either the based or free function space, our main results express the Whitehead product directly in terms of the Quillen minimal model of f. These results follow from a purely algebraic development in the setting of chain complexes of derivations of differential graded Lie algebras, which is of interest in its own right. We apply the results to study the Whitehead length of function space components.
