Nevanlinna Pair and Algebraic Hyperbolicity

Abstract

We introduce the notion of the Nevanlinna pair\textit{Nevanlinna pair} for a pair (X,D)(X, D), where XX is a projective variety and DD is an effective Cartier divisor on XX. This notion links and unifies the Nevanlinna theory, the complex hyperbolicity (Brody and Kobayashi hyperbolicity), the big Picard type extension theorem (more generally the Borel hyperbolicity), as well as the algebraic hyperbolicity. The key is to use the Nevanlinna theory on parabolic Riemann surfaces recently developed by P\v{a}un and Sibony.
