非单位$C^{*}$ -类别、(共)极限、交叉乘积和精确度

Non-unital $C^{*}$-categories, (co)limits, crossed products and exactness

Ulrich Bunke

摘要:

我们提供了一个参考的基本范畴性质的范畴(可能是非单位的)$\mathbb{C}$ -线性$*$ -范畴或$C^{*}$ -范畴,和(不一定是单位保持)函子。推广了具有$G$ -作用的代数的经典情形,将交叉积的构造推广到具有$G$ -作用的范畴.我们将证明交叉积函子保持精确序列和切除平方,并发送弱等价等价。

英文摘要:

We provide a reference for basic categorial properties of the categories of (possibly non-unital) $\mathbb{C}$-linear $*$-categories or $C^{*}$-categories, and (not necessarily unit-preserving) functors. Generalizing the classical case of algebras with $G$-action, we extend the construction of crossed products to categories with $G$-action. We will show that the crossed product functor preserves exact sequences and excisive squares and sends weak equivalences to equivalences.
