我们证明了抽象Cuntz半群构成一个闭的对称monoidal范畴。因此,给定Cuntz半群$S$和$T$,存在另一个Cuntz半群$[!【S,T】!】$扮演从$S$到$T$的态射的角色。应用于$C^{ast }$-代数$A$和$B$,半群$[![操作员名称{Cu}(A),操作员名称{Cu}(B)]!]在Cuntz半群双变理论的泛系数定理的类比中,$应被视为目标。摘要双变Cuntz半群在许多有趣的情形下是可计算的。我们还证明了$C^{ast }$-代数之间的零阶映射自然地定义了相应的双变Cuntz半群中的元素。
We show that abstract Cuntz semigroups form a closed symmetric monoidal category. Thus, given Cuntz semigroups $S$ and $T$, there is another Cuntz semigroup $[![ S,T ]!] $ playing the role of morphisms from $S$ to $T$. Applied to $C^{ast }$-algebras $A$ and $B$, the semigroup $[![ operatorname{Cu}(A),operatorname{Cu}(B) ]!] $ should be considered as the target in analogs of the universal coefficient theorem for bivariant theories of Cuntz semigroups. Abstract bivariant Cuntz semigroups are computable in a number of interesting cases. We also show that order-zero maps between $C^{ast }$-algebras naturally define elements in the respective bivariant Cuntz semigroup.
