Green 2-函子

Green 2-functors

Ivo Dell'Ambrogio

摘要:

我们通过定义环的适当概念,即Green 2-函子,扩展了arXiv:1808.04902中引入的Mackey 2-函子理论。在提供了我们的理论和丰富的例子的第一个结果,我们将展示如何从表示论和拓扑学熟悉的所有经典的绿色函子出现的decategorification,以各种方式,一些绿色2-函子发生在自然界中。

英文摘要:

We extend the theory of Mackey 2-functors introduced in arXiv:1808.04902 by defining the appropriate notion of rings, namely Green 2-functors. After providing the first results of our theory and abundant examples, we show how all classical Green functors familiar from representation theory and topology arise by decategorification, in various ways, of some Green 2-functor occurring in Nature.
