Neeman, Amnon2022-10-240020-9910http://hdl.handle.net/1885/276104In a 2006 article Schlichting conjectured that the negative K–theory of any abelian category must vanish. This conjecture was generalized in a 2019 article by Antieau, Gepner and Heller, who hypothesized that the negative K–theory of any category with a bounded t–structure must vanish. Both conjectures will be shown to be false.application/pdfen-AU© 2021 The authors202110.1007/s00222-021-01034-42021-11-28
