Ahlfors Currents and Symplectic Non-Hyperbolicity

Complex (affine) lines are a major object of study in complex geometry, but their symplectic aspects are not well understood.

Inspired by Duval's work on Ahlfors currents, we use them to perform a systematic study of complex lines in symplectic manifolds.

In particular, we generalize (by a different method and under topological assumptions) a result of Bangert on the existence of complex lines.

We show that Ahlfors currents control the asymptotic behavior of families of pseudoholomorphic curves, refining a result of Demailly.

Lastly, we show that the space of Ahlfors currents is convex.
