Stability conditions for quivers I King, Alastair


I will explain how geometric invariant theory gives rise to the numerical (and categorical) condition of theta-semistability for representations of quivers and describe its relationship to the classical slope semistability of Mumford and also to Schofield's construction of determinantal semi-invariants. I will also try to touch briefly on the conceptual evolution towards theta-torsion theories and the relationship with scattering diagrams (largely following Bridgeland).
