Abstract

Abstract Let M be the moduli space of complex Lagrangian submanifolds of a hyperKähler manifold X, and let ω̄ : 𝒜̂ → M be the relative Albanese over M. We prove that 𝒜̂ has a natural holomorphic symplectic structure. The projection ω̄ defines a completely integrable structure on the symplectic manifold 𝒜̂. In particular, the fibers of ω̄ are complex Lagrangians with respect to the symplectic form on 𝒜̂. We also prove analogous results for the relative Picard over M.

超Kähler流形中的复Lagrangians与相对Albanese

摘要设M为hyperKähler流形X的复拉格朗日子流形的模空间，设ω´:∈→M为M上的相对Albanese，证明了其具有自然全纯辛结构。投影ω定义了辛流形上的一个完全可积结构。特别地，ω的纤维是复拉格朗日量，相对于它的辛形式而言。我们还证明了M上相对皮卡德的类似结果。
