在前人工作的基础上,我们比较了V. Voevodsky在完备域k上引入的带转移同伦不变层范畴和M. Rost:前者是后者的一个完整子类别。利用D. C. Cisinski和一个非有效版本DM(k)的motivic复形范畴的作者最近的构造,我们证明了循环模构成DM(k)上自然t-结构的核心,推广了motivic复形上的同伦t-结构. 2010年数学学科分类:14 F42,(14 C15,14 C35)
Based on previous works, we compare over a perfect field k the category of homotopy invariant sheaves with transfers introduced by V. Voevodsky and the category of cycle modules introduced by M. Rost: the former is a full subcategory of the latter. Using the recent construction by D.C. Cisinski and the author of a non effective version DM(k) of the category of motivic complexes, we show that cycle modules form the heart of a natural t-structure on DM(k), generalizing the homotopy t-structure on motivic complexes. 2010 Mathematics Subject Classification: 14F42, (14C15, 14C35)
