Conjecture 6.2

Let ℳ¯\overline{{\cal M}} be a compactified moduli space of complex deformations of a simply-connected Calabi–Yau nn-fold XX, and let p∈ℳ¯p\in\overline{{\cal M}} be a large complex structure limit point (see [23] for the precise Hodge-theoretic definition of this notion). Let (Xi,gi)(X_{i},g_{i}) be a sequence of Calabi–Yau manifolds with Ricci-flat Kähler metric which are complex deformations of XX, with the sequence [Xi]∈ℳ¯[X_{i}]\in\overline{{\cal M}} converging to pp, and C1≥D​i​a​m​(Xi)≥C2>0C_{1}\geq Diam(X_{i})\geq C_{2}>0 for all ii. Then a subsequence of this sequence converges to a metric space (X∞,d∞)(X_{\infty},d_{\infty}), where X∞X_{\infty} is homeomorphic to SnS^{n}. Furthermore, d∞d_{\infty} is induced by a Riemannian metric on X∞∖ΔX_{\infty}\setminus\Delta, where Δ⊆X∞\Delta\subseteq X_{\infty} is a set of codimension 2.
