...lar, Λ and Λ′ are derived equivalent. (d) If Λ is symmetric then Λ′ is symmetric. We note that there are related works by Dugas [6] concerning derived equivalences of symmetric algebras and by Mizuno =-=[23]-=- concerning derived equivalences of self-injective quivers with potential. The category of perfect complexes over a symmetric algebra is 0-Calabi-Yau, hence the derived equivalences in part (c) can be...
