摘要

我们在具有核的正规范畴中引入了部分对易子的概念,作为最近引入的部分对易性概念的对易子。通过对Huq换向子的定义进行轻微修改来定义部分换向子,并且它们在统一上下文中是一致的。我们证明Huq换向器的一些基本性质仍然可以恢复。特别地,当且仅当态射部分可交换时,部分对易子消失,并且在有限极限的正规范畴中,它总是存在并且可以通过极限得到,就像在绝对情况下一样。作为应用,我们研究了W. Rump意义下l -代数\(\textsf{LAlg}\)范畴中的部分对易子。

Partial commutators

We introduce a notion of partial commutator in the context of a normal category with cokernels, as the commutator resulting from the recently introduced notion of partial commutativity. The partial commutator is defined by making slight modifications to the definition of the Huq commutator, and they agree in the unital context. We show that some fundamental properties of the Huq commutator can still be recovered. In particular, the partial commutator vanishes if and only if the morphisms partially commute, and in a normal category with finite colimits, it always exists and can be obtained via colimits as it is the case in absolute settings. As an application, we investigate partial commutators in the category \(\textsf{LAlg}\) of L-algebras in the sense of W. Rump.

期刊介绍: Algebra Universalis publishes papers in universal algebra, lattice theory, and related fields. In a pragmatic way, one could define the areas of interest of the journal as the union of the areas of interest of the members of the Editorial Board. In addition to research papers, we are also interested in publishing high quality survey articles.
