设 / : X - > S 为保护品种之间的拉格朗日纤维。我们证明如果 S 是光滑的,则 R% Ox ¥ Q^。假设 X 是不可约辛流形或 K3 面上半稳定扭转自由滑轮的某个模空间,霍奇数满足 hP4(S) = hP^iF"),其中 n = dim 5。如果 5 ^ F1 且 X 是不可约辛流形,则存在 X 的 Kuranishi 空间的超曲面 Mf,使得 Kuranishi 族的每个成员 over Mf 承认 IP 上的拉格朗日纤维”。
Let / : X - > S be a Lagrangian fibration between protective varieties. We prove that R% Ox ¥ Q^ if S is smooth. Suppose that X is an irreducible symplectic manifold or a certain moduli space of semistable torsion free sheaves on a K3 surface, the Hodge numbers satisfy hP4(S) = hP^iF"), where n = dim 5. If 5 ^ F1 and X is an irreducible symplectic manifold, there exists a hypersurface Mf of the Kuranishi space of X such that every member of the Kuranishi family over Mf admits a Lagrangian fibration over IP".
