Kaif Hilman

AI总结:

本文在轨道范畴上的参数化同伦理论框架下发展了可表现性概念,通过相关拉直刻画参数化可表现范畴,推导出参数化伴随函子定理与局部化结果,并应用于等变代数K-理论中参数化非交换动机范畴的构造。

摘要:

本文在 Barwick-Dotto-Glasman-Nardin-Shah 的参数化同伦理论框架下,发展了轨道范畴上的可表现性概念。我们提出并证明了一个定理,通过其相关的拉直(straightening)来刻画参数化可表现范畴。由此,我们从非参数化版本推导出参数化伴随函子定理,证明了多种局部化结果,并记录了此处可表现性概念与乘法问题的相互作用。该理论在等变同伦理论等领域具有研究价值,我们将在配套工作中应用它,为等变代数 K-理论构造参数化非交换动机范畴。

英文摘要:

In this paper, we develop the notion of presentability in the parametrised homotopy theory framework of Barwick-Dotto-Glasman-Nardin-Shah over orbital categories. We formulate and prove a characterisation of parametrised presentable categories in terms of its associated straightening. From this we deduce a parametrised adjoint functor theorem from the unparametrised version, prove various localisation results, and we record the interactions of the notion of presentability here with multiplicative matters. Such a theory is of interest for example in equivariant homotopy theory, and we will apply it in a companion work to construct the category of parametrised noncommutative motives for equivariant algebraic K-theory.
