Abstract / Bemerkung
We show that the space of invariants for the Weil representation for discriminant groups which contain self-dual isotropic subgroups is spanned by the characteristic functions of the self-dual isotropic subgroups. As an application, we construct modular units for certain orthogonal groups in signature using Borcherds products.
