论文摘要
在本说明中,我们建立在范格德曼和Voisin的参数上,以证明Matsushita的猜想是,不可减至的Hyperkähler歧管的Lagrangian振动是同骨或最大变化。我们还完成了Voisin的部分结果,内容涉及拉格朗日纤维曲线的扭转点的密度。
In this note we build on the arguments of van Geemen and Voisin to prove a conjecture of Matsushita that a Lagrangian fibration of an irreducible hyperkähler manifold is either isotrivial or of maximal variation. We also complete a partial result of Voisin regarding the density of torsion points of sections of Lagrangian fibrations.
