For general Calabi-Yau hypersurfaces, the dependence on complex and K¨ahler structure is somewhat … A Lagrangian fibration of a symplectic manifold M is a fibration where all of the fibres are Lagrangian submanifolds. Since M is even-dimensional we can take local coordinates (p1,…,pn, q ,…,q ), and by Darboux's theorem the symplectic form ω can be, at least locally, written as ω = ∑ dpk ∧ dq , where d denotes the exterior derivative and ∧ denotes the exterior product. This form is called the Poincaré two-form or the canonical two-form. Using this set-up we can locally think of M as bein…
