Abstract

In non-archimedean setting, we establish a Lehto--Virtanen-type theorem for a morphism from the punctured Berkovich closed unit disk D{0}\overline{\mathsf{D}}\setminus\{0\} in the Berkovich affine line to the Berkovich projective line P1\mathsf{P}^1 having an isolated essential singularity at the origin, and then establish a big Picard-type theorem for such an open subset Ω\Omega in the Berkovich projective space PN\mathsf{P}^N of any dimension NN that the family of all morphisms from D{0}\overline{\mathsf{D}}\setminus\{0\} to Ω\Omega is normal in a non-archimedean Montel's sense. As an application of the latter theorem, we see a big Brody-type hyperbolicity of the Berkovich harmonic Fatou set of an endomorphism of PN\mathsf{P}^N of degree >1>1.
