Abstract

We study the deformation behavior of compact hyperbolic complex manifolds. Let π:XΔ\pi:\mathcal{X}\rightarrow \Delta be a smooth family of compact complex manifolds over the unit disk in C\mathbb{C}, and HH a compact hyperbolic complex manifold. Then the HH-locus {tΔ:XtH}\{t\in\Delta: X_t\cong H\} is either at most a discrete subset of Δ\Delta or the whole Δ\Delta. For a smooth family over a compact Riemann surface YY, its HH-locus is either at most finite or the whole YY. Furthermore, if YY is isomorphic to P1\mathbb{P}^1 or an elliptic curve, then we conjecture that the HH-locus is empty or the whole YY.
