关于有理动机同伦范畴

On the rational motivic homotopy category

Frédéric Déglise, Jean Fasel, Adeel A. Khan, Fangzhou Jin

摘要:

研究了一般基概型上有理动机稳定同伦范畴的结构。我们的第一类结果涉及六种运算:我们证明了SH_Q的绝对纯性、可构造对象的稳定性和Grothendieck-Verdier对偶性。其次,我们证明了SH_Q是正则SL-定向的;我们将SH_Q与有理Milnor-Witt动机范畴进行了比较;我们将有理双变A^1-理论与Chow-Witt群联系起来。这些结果是从SH[1/2]的负部分的类似陈述导出的。

英文摘要:

We study the structure of the rational motivic stable homotopy category over general base schemes. Our first class of results concerns the six operations: we prove absolute purity, stability of constructible objects, and Grothendieck-Verdier duality for SH_Q. Next, we prove that SH_Q is canonically SL-oriented; we compare SH_Q with the category of rational Milnor-Witt motives; and we relate the rational bivariant A^1-theory to Chow-Witt groups. These results are derived from analogous statements for the minus part of SH[1/2].
