oai:localhost:PNK-74182023-04-03T03:36:34Z Torsion Pairs and Ringel Duality for Schur Algebras Karin, Erdmann Stacey, Law basic projective A–modules P torsion submodules of P CC BY Let A be a finite-dimensional algebra over an algebraically closed field. We use a functorial approach involving torsion pairs to construct embeddings of endomorphism algebras of basic projective A–modules P into those of the torsion submodules of P. As an application, we show that blocks of both the classical and quantum Schur algebras S(2,r) and Sq(2,r) in characteristic p > 0 are Morita equivalent as quasi-hereditary algebras to their Ringel duals if they contain 2pk simple modules for some k. 2023-04-03T03:11:31Z 2023-04-03T03:11:31Z 2021 Book https://link.springer.com/article/10.1007/s10468-021-10098-y https://dlib.phenikaa-uni.edu.vn/handle/PNK/7418 en application/pdf Springer |
