Ideal approximation in $n$ -exangulated categories

Yucheng Wang, Jiaqun Wei

In this paper, we study the ideal approximation theory associated to almost $n$ -exact structures in the $n$ -exangulated category. The notions of $n$ -ideal cotorsion pairs and $n$ -$…

Tingting Li, Jianlong Chen, Sanzhang Xu

Let $C$ be an additive category with an involution $*$ . Suppose that $φ : X \to X$ is a morphism of $C$ with core inverse $φ^{\co} : X \rightarrow X$…
