非交换动机的A1-homotopy理论

A1-homotopy theory of noncommutative motives

Goncalo Tabuada

摘要:

在这篇文章中,我们继续发展的理论,非交换动机。构造了A1-同伦非交换基模范畴,描述了它们的泛性质,并利用Karoubi-Villamayor的K-理论(KV)和Weibel的同伦K-理论(KH)计算了它们的态射谱.作为应用,我们得到了KV,KH上所有自然变换的完全分类.这导致了一个流线型的建设韦伯的同伦陈特征KV周期循环同调。一路上,我们扩展Dwyer-Friedlander的etale K-理论的非对易世界,并开发的通用程序,迫使函子保持过滤同伦余极限。

英文摘要:

In this article we continue the development of a theory of noncommutative motives. We construct categories of A1-homotopy noncommutative motives, described their universal properties, and compute their spectra of morphisms in terms of Karoubi-Villamayor's K-theory (KV) and Weibel's homotopy K-theory (KH). As an application, we obtain a complete classification of all the natural transformations defined on KV, KH. This leads to a streamlined construction of Weibel's homotopy Chern character from KV to periodic cyclic homology. Along the way we extend Dwyer-Friedlander's etale K-theory to the noncommutative world, and develop the universal procedure of forcing a functor to preserve filtered homotopy colimits.
