摘要

对于具有严格$G$-作用的$C^{*}$-范畴,我们构造了等变粗同调理论的例子。为此,我们首先引入了在bornological粗空间上控制的$C^{*}$-范畴中对象的Roe范畴的版本,然后应用同调函子。然后利用这些等变粗同调理论来验证轨道范畴上的某些函子是CP函子。这一事实对装配映射的内射性有影响。

Topological equivariant coarse K-homology
For a $C^{*}$-category with a strict $G$-action we construct examples of equivariant coarse homology theories. To this end we first introduce versions of Roe categories of objects in $C^{*}$-categories which are controlled over bornological coarse spaces, and then apply a homological functor. These equivariant coarse homology theories are then employed to verify that certain functors on the orbit category are CP-functors. This fact has consequences for the injectivity of assembly maps.
