Hyperbolicity of cyclic covers and complements

Algebraic Geometry 2018-06-19 v3 Complex Variables

Abstract

We prove that a cyclic cover of a smooth complex projective variety is Brody hyperbolic if its branch divisor is a generic small deformation of a large enough multiple of a Brody hyperbolic base-point-free ample divisor. We also show the hyperbolicity of complements of those branch divisors. As an application, we find new examples of Brody hyperbolic hypersurfaces in Pn+1\mathbb{P}^{n+1} that are cyclic covers of Pn\mathbb{P}^n.
