DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UNYONTC/15/"
 >Modular forms and invariant theory</a>\nby Gerard van der Geer as part of
  Upstate New York Online Number Theory Colloquium\n\n\nAbstract\nSiegel an
 d Teichmueller modular forms of genus g are generalizations\nof the usual 
 elliptic modular forms\, the case g=1\, but live on the\nmoduli spaces of 
 abelian varieties and curves of genus g. These forms\, \nare just as intri
 guing\, but more difficult to construct.\nWe intend to show how one can us
 e invariant theory to describe in \nprinciple all such modular forms for g
 enus 2 and 3 explicitly.\nThis is joint work with Fabien Clery and Carel F
 aber.\n
