Rationally connected foliations on surfaces

Algebraic Geometry 2008-11-21 v1

Abstract

In this short note we study foliations with rationally connected leaves on surfaces. Our main result is that on surfaces there exists a polarisation such that the Harder-Narasimhan filtration of the tangent bundle with respect to this polarisation yields the maximal rationally quotient of the surface.
