  • Independent parameters for special instanton bundles on P^{2n+1} (Pre-published Version) 

    Hoffmann, Norbert (Elsevier, 2011)
    Motivated by Yang-Mills theory in 4n dimensions, and generalizing the notion due to Atiyah, Drinfeld, Hitchin and Manin for n = 1, Okonek, Spindler and Trautmann introduced instanton bundles and special instanton bundles ...
  • Moduli schemes of generically simple Azumaya modules 

    Hoffmann, Norbert; Stuhler, Ulrich (Documenta Mathematica, 2005)
    Let A be an Azumaya algebra over a smooth projective variety X or more generally, a torsion free coherent sheaf of algebras over X whose generic fiber is a central simple algebra. We show that generically simple torsion ...
  • Torelli theorem for the Deligne-Hitchin moduli space (Pre-published version) 

    Biswas, Indranil; Gómez, Tomás L.; Hoffmann, Norbert; Logares, Marina (Springer Verlag, 2009)
    Fix integers g ≥ 3 and r ≥ 2, with r ≥ 3 if g = 3. Given a compact connected Riemann surface X of genus g, let M DH (X) denote the corresponding SL(r,C) Deligne–Hitchin moduli space. We prove that the complex analytic ...
