Query: Uniruled symplectic divisors   This is a paper devoted to the symplectic birational geometry program where
many basic notions are defined in terms of genus 0 GW invariants. We show that
the existence of a positive uniruled symplectic divisor often implies that the
ambient manifold has a nonzero uniruled genus 0 GW invariant, hence is uniruled
as well. This confirms a part of the dichotomy on uniruled symplectic divisors.
In addition, it gives a rather general construction of uniruled symplectic
manifolds, generalizing some beautiful results of McDuff.
