چکیده
Let X be an irreducible symplectic manifold and Def(X) the Kuranishi space. Assume that X admits a Lagrangian fibration. We prove that X can be deformed preserving a Lagrangian fibration. More precisely, there exists a smooth hypersurface H of Def(X) such that the restriction family X ×Def(X) H admits a family of Lagrangian fibrations over H.

Deformations of holomorphic Lagrangian fibrations
Let X → Pn be a 2n-dimensional projective holomorphic symplectic manifold admitting a Lagrangian fibration over Pn. Matsushita proved that the fibration can be deformed in a codimension one family in the moduli space Def(X) of deformations of X. We extend his result by proving that if the Lagrangian fibration admits a section, then there is a codimension two family of deformations which also pr...
متن کاملClassification of Lagrangian Fibrations over a Klein Bottle
This paper completes the classification of regular Lagrangian fibrations over compact surfaces. [13] classifies regular Lagrangian fibrations over T. The main theorem in [8] is used to in order to classify integral affine structures on the Klein bottle K and, hence, regular Lagrangian fibrations over this space.
متن کاملModuli of Coassociative Submanifolds and Semi-Flat Coassociative Fibrations
We show that the moduli space of deformations of a compact coassociative submanifold L has a natural local embedding as a submanifold of H(L,R). We show that a G2-manifold with a T -action of isomorphisms such that the orbits are coassociative tori is locally equivalent to a minimal 3-manifold in R with positive induced metric where R ∼= H(T ,R). By studying minimal surfaces in quadrics we show...
متن کاملTwisted Fourier-Mukai transforms for holomorphic symplectic fourfolds
We apply the methods of Căldăraru to construct a twisted FourierMukai transform between a pair of holomorphic symplectic four-folds. More precisely, we obtain an equivalence between the derived category of coherent sheaves on a certain four-fold and the derived category of twisted sheaves on its ‘mirror’ partner. As corollaries, we show that the two spaces are connected by a one-parameter famil...
متن کاملExamples of Special Lagrangian Fibrations
Of late there has been a great deal of interest in special Lagrangian submanifolds and manifolds fibred in special Lagrangian submanifolds, motivated by the Strominger-Yau-Zaslow conjecture [29]. One of the basic approaches to finding examples is to exploit symmetries of the ambient manifold. If X is a (non-compact) n-dimensional Calabi-Yau manifold with Kähler form ω and nowhere vanishing holo...
