Pullbacks of hyperplane sections for Lagrangian fibrations are primitive

Kamenova L., Verbitsky M.
Let p: M -> B be a Lagrangian fibration on a hyperkahler manifold of maximal holonomy (also known as IHS), and H the generator of the Picard group of B. We prove that the pullback p∗(H) is a primitive class on M.
