  • Generalized vector bundles on curves (Pre-published version) 

    Hoffmann, Norbert; Stuhler, Ulrich; Jahnel, Joerg (de Gruyter, 1998)
    In their paper [14] G. Harder and M.S. Narasimhan (and independently D. Quillen) have constructed a canonical flag of subbundles on any vector bundle on a complete smooth algebraic curve over a field. This flag measures ...
  • 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 ...
