Division formulas on projective varieties
  We introduce a division formula on a possibly singular projective subvariety $X$ of complex projective space $\Pk^N$, which, e.g., provides explicit representations of solutions to various polynomial division problems on the affine part of $X$. Especially we consider a global effective version of the Brian\c con-Skoda-Huneke theorem.
