Mutating signed -exceptional sequences
Buan, Aslak Bakke; Marsh, Bethany Rose (Journal article; Peer reviewed, 2023)We establish some properties of τ -exceptional sequences for finite-dimensional algebras. In an earlier paper, we established a bijection between the set of ordered support τ -tilting modules and the set of complete ... -
Tau-exceptional sequences
Buan, Aslak Bakke; Marsh, Bethany Rose (Journal article; Peer reviewed, 2021)We introduce the notions of τ-exceptional and signed τ-exceptional sequences for any finite dimensional algebra. We prove that for a fixed algebra of rank n, and for any positive integer , there is a bijection between ...
