| Research Abstract |
We show that the base space of a Lagrangian fibration is a projective space if the source symplectic variety satisfies certain numerical conditions. We obtain the necessary and sufficient condition of existence of a Lagrangian fibration for all known examples. We also show smoothness of components of the relative moduli space of aLagrangian fibration which parametrize invertible sheaves on each fibre.
