Classifying Nakayama algebras with a braid group action on -exceptional sequences
Maximilian Kaipel, Håvard Utne Terland
We characterise those basic and connected Nakayama algebras for which the mutation of -exceptional sequences respects the braid group relations. We show that this is the cas…

Mutating ordered -rigid modules with applications to Nakayama algebras
Aslak B. Buan, Maximilian Kaipel, Håvard U. Terland
A mutation operation for -exceptional sequences of modules over any finite-dimensional algebra was recently introduced, generalising the mutation for exceptional sequences of mo…

Reduction Techniques to Identify Connected Components of Mutation Quivers
Håvard Utne Terland
Important objects of study in -tilting theory include the -tilting pairs over an algebra on the form , with being a path algebra and an admissible ideal. In th…
