Transfer of derived equivalences from subalgebras to endomorphism algebras II

Abstract

We investigate derived equivalences between subalgebras of some $\hat{I}¦$-Auslander-Yoneda algebras from a class of $n$-angles in weakly $n$-angulated categories. The derived equivalences are obtained by transferring subalgebras induced by $n$-angles to endomorphism algebras induced by approximation sequences. Then we extend our constructions \cite{BP} to $n$-angle cases. Finally, we give an explicit example to illustrate our result.
