导出表示论与域的代数K理论

Derived Representation Theory and the Algebraic K-theory of Fields

Gunnar Carlsson

摘要:

我们描述了一个以投射有限群为输入的构造,当应用于几何域F的绝对伽罗瓦群时,在某些情况下与F的代数K理论一致。我们证明了它在拓扑生成的交换绝对伽罗瓦群中是一致的,并猜想它对所有几何域都是一致的。我们还讨论了建设的性质,包括与无限离散群的表示论的关系。

英文摘要:

We describe the construction which takes as input a profinite group, which when applied the the absolute Galois group of a geometric field F agrees in some cases with the algebraic K-theory of F. We prove that it agrees in the case of a topologically finitely generated abelian absolute Galois group, and conjecture that it agrees for all geometric fields. We also discuss properties of the construction, including relationships with the representation theory of infinite discrete groups.
