Lemma 3.2.

dimℝS¯=n\dim_{\mathbb{R}}\bar{S}=n, and there is a constant θ0∈ℝ\theta_{0}\in\mathbb{R} such that ωE|S¯=0\omega_{E}|_{\bar{S}}=0 and Im​e−1​θ0​ΩE|S¯=0.{\rm Im}e^{\sqrt{-1}\theta_{0}}\Omega_{E}|_{\bar{S}}=0. Moreover, SS is a special lagrangian submanifold of phase θ0\theta_{0} in (X,ω0,Ω0)(X,\omega_{0},\Omega_{0}), i.e. dimℝS=n\dim_{\mathbb{R}}S=n,

ω0|S≡0,andIm​e−1​θ0​Ω0|S=0.\omega_{0}|_{S}\equiv 0,\ \ {\rm and}\ \ {\rm Im}e^{\sqrt{-1}\theta_{0}}\Omega_{0}|_{S}=0.
