For a non-positive (topologically) homologically smooth dg $k$-algebra $A$ whose zeroth cohomology is finite-dimensional, or for a non-positive proper dg $k$-algebra $A$, the one-to-one correspondence between isomorphism classes of basic silting objects of $\\mathsf{per}(A)$ and algebraic $t$-structures on $\\mathsf{D}_{\\rm fd}(A)$ was already known. The main result of this paper generalizes the above two results to locally finite non-positive dg $k$-algebras.", "revisions": [ { "version": "v1", "updated": "2023-12-29T13:22:49.000Z" } ], "analyses": { "subjects": [ "16E35", "16E45", "18G80" ], "keywords": [ "structures", "correspondence", "basic silting objects", "isomorphism classes", "locally finite non-positive dg algebra" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
