(HoRSe seminar) 'Stability conditions on the local projective plane and $ \Gamma_1(3) $-action I'
We report on joint work with Arend Bayer on the space of stability conditions for the canonical bundle on the projective plane. We will describe a connected component of this space, generalizing and completing a previous construction of Bridgeland. In particular, we will see how this space is related to classical results of Drezet-Le Potier on stable vector bundles on the projective plane. Using this, we can determine the group of autoequivalences of the derived category. As a consequence, we can identify a $ \Gamma_1(3) $-action on the space of stability conditions, which will give a global picture of mirror symmetry for this example. In the second hour we will give some details on the proof of the main theorem.
