Quiver bundles

In this talk, I will first review the “classical” formalism of quiver representations, with a view on sheaves and instantons on projective manifolds. Then, I will give a survey on results on quiver bundles on projective manifolds and their moduli spaces. At the end, I will present joint work with Garcia-Prada and Heinloth on the motive of the moduli space of Higgs bundles of rank four and odd degree on a compact Riemann surface.
