Classifying Nakayama algebras with a braid group action on $I ¨ $ -exceptional sequences

Maximilian Kaipel, HÃ¥vard Utne Terland

We characterise those basic and connected Nakayama algebras $I^$ for which the mutation of $I ¨ $ -exceptional sequences respects the braid group relations. We show that this is the c…

Mutating ordered $I ¨ $ -rigid modules with applications to Nakayama algebras

Aslak B. Buan, Maximilian Kaipel, HÃ¥vard U. Terland

A mutation operation for $I ¨ $ -exceptional sequences of modules over any finite-dimensional algebra was recently introduced, generalising the mutation for exceptional sequences of m…
