  • Semi-continuity of stability for sheaves and variation of Gieseker moduli spaces 

    Greb, Daniel; Ross, Julius Andrew; Toma, Matei (De GruyterJournal für die reine und angewandte Mathematik, 2016)
    We investigate a semi-continuity property for stability conditions for sheaves that is important for the problem of variation of the moduli spaces as the stability condition changes. We place this in the context of a notion ...

  • Variation of Gieseker moduli spaces via quiver GIT 

    Greb, Daniel; Ross, Julius Andrew; Toma, Matei (Mathematical Sciences PublishersGeometry & Topology, 2016)
    We introduce a notion of stability for sheaves with respect to several polarisations that generalises the usual notion of Gieseker-stability. We prove, under a boundedness assumption, which we show to hold on threefolds ...
