Query: A weighted version of Zariski's hyperplane section theorem and
  fundamental groups of complements of plane curves   We formulate and prove a weighted version of Zariski's hyperplane section
theorem on the topological fundamental groups of the complements of
hypersurfaces in a projective space. As an application, we calculate
fundamental groups of the complements of certain singular projective plane
curves.
