This construct ion is similar to the Happel-Reiten-Smalo tilt of a t-structure with respe ct to a torsion pair in its heart and it induces a bijection between inter mediate co-t-structures and complete cotorsion pairs. For a finite dimensi onal algebra this introduces a new component to the numerous existing bije ctions studied in tau-tilting theory and in silting theory\, that is the b ijections between intermediate algebraic t-structures\, functorially finit e torsion pairs\, two-term silting complexes\, and so on. \n\nBased on joi nt work with David Pauksztello.\n LOCATION:https://researchseminars.org/talk/TRAC/23/ END:VEVENT END:VCALENDAR
