互易层的纯性

Purity of reciprocity sheaves

Shuji Saito

摘要:

本文证明了Kahn-Saito-Yamazaki关于互易层的一个猜想。这是通过扩展Voevodsky的基本结果同伦不变量(前)层转移到其推广,互易层和立方不变层的背景下,理论的模量(前)滑轮转移。本文的主要结果将对模三角化动机范畴的主要性质的推导起到重要作用,模三角化动机范畴是将Voevodsky的三角化动机范畴扩展到包含非同伦不变量动机现象的一个新的三角化范畴.

英文摘要:

The purpose of this paper is to prove a conjecture on reciprocity sheaves by Kahn-Saito-Yamazaki. This is accomplished by extending Voevodsky's fundamental results on homotopy invariant (pre)sheaves with transfers to its generalizations, reciprocity sheaves and cube-invariant sheaves in the context of theory of modulus (pre)sheave with transfers. The main results of this paper is expected to play a crucial role in deducing the main properties of the triangulated category of motives with modulus, which is a new triangulated category enlarging Voevodsky's triangulated category of motives to encompass non homotopy invariant motivic phenomena.
