Definition 7.4.

Let VV be a Kähler space with only log terminal singularities. VV is said to be ℚ\mathbb{Q}-CY, iff there is some multiple N′N^{\prime} of i​n​d​e​x​(X)index(X) such that H0​(V,ωV[N′])=ℂ​αH^{0}(V,\omega^{[N^{\prime}]}_{V})=\mathbb{C}\alpha, where α\alpha is a global generator of ωV[N′]\omega^{[N^{\prime}]}_{V}.
