τ-slice algebras of n-translation algebras and quasi n-Fano algebras

In this paper, we show that the $n$-APR tilts of dual $\tau$-slice algebras of acyclic stable $n$-translation algebras are realized as $\tau$-mutations. Such dual $\tau$-slice algebras are quasi $(n-1)$-Fano when the $n$-translation algebra is Koszul, and a recursive construction of higher quasi Fano algebras for quasi $n$-Fano algebra obtained in this way is given. The $\tau_n$-closure and $\nu_n$-closure of such algebras are studied and we show that for an acyclic dual $n$-translation algebras with bound quiver $Q^{\perp}$, the Auslander-Reiten quivers of its $\tau_n$-closures are truncation of the quiver $\mathbb{Z}|_n Q^{\perp}$, and the Auslander-Reiten quiver of its $\nu_n$-closure is $\mathbb{Z}|_n Q^{\perp}$ when it is $n$-representation infinite.
