Big Picard theorem for moduli spaces of polarized manifolds

Abstract

Consider a smooth projective family of complex polarized manifolds with semi-ample canonical sheaf over a quasi-projective manifold VV. When the associated moduli map VPhV\to P_h from the base to coarse moduli space is quasi-finite, we prove that the generalized big Picard theorem holds for the base manifold VV: for any projective compactification YY of VV, any holomorphic map f:Δ{0}Vf:\Delta-\{0\}\to V from the punctured unit disk to VV extends to a holomorphic map of the unit disk Δ\Delta into YY. This result generalizes our previous work on the Brody hyperbolicity of VV (i.e. there are no entire curves on VV), as well as a more recent work by Lu-Sun-Zuo on the Borel hyperbolicity of VV (i.e. any holomorphic map from a quasi-projective variety to VV is algebraic). We also obtain generalized big Picard theorem for bases of log Calabi-Yau families.
