$n$-APR tilting and $τ$-mutations (1901.08465v2)

Abstract: APR tilts for path algebra $kQ$ can be realized as the mutation of the quiver $Q$ in $\mathbb Z Q$ with respect to the translation. In this paper, we show that we have similar results for the quadratic dual of truncations of $n$-translation algebras, that is, under certain condition, the $n$-APR tilts of such algebras are realized as $\tau$-mutations.For the dual $\tau$-slice algebras with bound quiver $Q^{\perp}$, we show that their iterated $n$-APR tilts are realized by the iterated $\tau$-mutations in $\mathbb Z|{n-1}Q^{\perp}$.
