论德利涅-芒福德书库的动机

On motives for Deligne-Mumford stacks

B. Toen

摘要:

我们定义和比较两种不同的定义周动机Deligne-Mumford栈,与两种定义的周环。我们证明的主要结果是,这两个类别的动机是等价的代数簇的通常类别的动机,但与这两个理论相关的一个给定的堆栈的动机是不同构的。我们还将给出一些与一些aleglobal堆栈相关的动机的例子。

英文摘要:

We define and compare two different definitions of Chow motives for Deligne-Mumford stacks, associated with two definitions of Chow rings. The main result we prove is that both categories of motives are equivalent to the usual category of motives of algebraic varieties, but the motives of a given stack associated with both theories are not isomorphic. We will also give some examples of motives associated with some alegbraic stacks.
