Mutation of torsion pairs for finite-dimensional algebras
Lidia Angeleri Hügel, Rosanna Laking, Francesco Sentieri
We study the lattice of torsion pairs in the category of finitely generated modules over an artinian ring . It was shown by the authors in p…

Torsion pairs via the Ziegler spectrum
Lidia Angeleri Hügel, Rosanna Laking, Francesco Sentieri
We establish a bijection between torsion pairs in the category of finite-dimensional modules over a finite-dimensional algebra A and pairs (Z, I) formed by a closed rigid set Z in…
