Query: Vanishing homology of projective hypersurfaces with 1-dimensional
  singularities   We introduce and study the vanishing homology of singular projective
hypersurfaces. We prove its concentration in two levels in case of
1-dimensional singular locus $\Sigma$, and moreover determine the ranks of the
nontrivial homology groups. These two groups depend on the monodromy at special
points of $\Sigma$ and on the effect of the monodromy of the local system over
its complement.
