Query: Local geometry of symplectic divisors with applications to contact torus
  bundles   In this note we study the contact geometry of symplectic divisors. We show
the contact structure induced on the boundary of a divisor neighborhood is
invariant under toric and interior blow-ups and blow-downs. We also construct
an open book decomposition on the boundary of a concave divisor neighborhood
and apply it to the study of universally tight contact structures of contact
torus bundles.
