$mathbb Z Q$ type constructions in higher representation theory

Let $Q$ be an acyclic quiver, it is classical that certain truncations of the translation quiver $mathbb Z Q$ appear in the Auslander-Reiten quiver of the path algebra $kQ$. We introduce the $n$-translation quiver $mathbb Z|_{n-1} Q$ as a generalization of the $mathbb Z Q$ construction in our recent study on $n$-translation algebras. In this paper, we introduce $n$-slice algebra and show that for certain $n$-slice algebra $Gamma$, % of global dimension $n$, the quiver $mathbb Z|_{n-1} Q$ can be used to describe the $tau_n$-closure of $DGamma$ and $tau_n^{-1}$-closure of $Gamma$ in its module category and the $ u_n$-closure of $Gamma$ in the derived category.
