Chow动机与非交换动机

Chow motives versus non-commutative motives

Goncalo Tabuada

摘要:

在这篇文章中,我们形式化和提高Kontsevich的美丽的洞察力,周动机可以嵌入到非交换的因式分解后的行动泰特对象。我们说明了这一结果的潜力,通过开发其多方面的应用:(1)舒尔和木村有限性的概念承认一个适当的扩展领域的非交换动机;(2)Gillet-Soule的motivic措施承认一个扩展的Grothendieck环的非交换动机;(3)某些motivic zeta函数承认一个内在的建设范畴内的非交换动机。

英文摘要:

In this article we formalize and enhance Kontsevich's beautiful insight that Chow motives can be embedded into non-commutative ones after factoring out by the action of the Tate object. We illustrate the potential of this result by developing three of its manyfold applications: (1) the notions of Schur and Kimura finiteness admit an adequate extension to the realm of non-commutative motives; (2) Gillet-Soule's motivic measure admits an extension to the Grothendieck ring of non-commutative motives; (3) certain motivic zeta functions admit an intrinsic construction inside the category of non-commutative motives.
