We further prove that derived-discreteness is equivalent to silting-discreteness within this family and determine precisely when these equivalent conditions are strictly stronger than $\tau$-tilting finiteness. Comments: 29 pages. Substantially revised version. In addition to the classification of $τ$-tilting finite Borel--Schur algebras, we now classify the silting-discrete and derived-discrete cases Subjects: Representation Theory (math.RT) Cite as: arXiv:2310.00358 [math.RT] (or arXiv:2310.00358v3 [math.RT] for this version) https://doi.org/10.48550/arXiv.2310.00358 Focus to learn more arXiv-issued DOI via DataCite Submission history From: Qi Wang [ view email ] [v1] Sat, 30 Sep 2023 12:29:56 UTC (25 KB) [v2] Sat, 30 Mar 2024 13:34:08 UTC (28 KB) [v3] Thu, 27 Aug 2026 05:38:54 UTC (29 KB) Full-text links: Access Paper: View PDF HTML (experimental) TeX Source view license Current browse context: math.RT < prev | next > new | recent | 2023-10 Change to browse by: math References & Citations SciX Google Scholar Semantic Scholar export BibTeX citation Bookmark Bibliographic Tools Bibliographic and Citation Tools Bibliographic Explorer Toggle Bibliographic Explorer ( What is the Explorer? ) Connected Papers Toggle Connected Papers ( What is Connected Papers? ) Litmaps Toggle Litmaps ( What is Litmaps? ) scite.ai Toggle scite Smart Citations ( What are Smart Citations? ) Code, Data, Media Code, Data and Media Associated with this Article alphaXiv Toggle alphaXiv ( What is alphaXiv? ) Links to Code Toggle CatalyzeX Code Finder for Papers ( What is CatalyzeX? ) DagsHub Toggle DagsHub ( What is DagsHub? ) GotitPub Toggle Gotit.pub ( What is GotitPub? ) Huggingface Toggle Hugging Face ( What is Huggingface? ) ScienceCast Toggle ScienceCast ( What is ScienceCast? ) Demos Demos Replicate Toggle Replicate ( What is Replicate? ) Spaces Toggle Hugging Face Spaces ( What is Spaces? ) Spaces Toggle TXYZ.AI ( What is TXYZ.AI? ) Related Papers Recommenders and Search Tools Link to Influence Flower Influence Flower ( What are Influence Flowers? ) Core recommender toggle CORE Recommender ( What is CORE? ) Author Venue Institution Topic About arXivLabs arXivLabs: experimental projects with community collaborators arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.
