On a characterization of an abelian variety in the classification theory of algebraic varieties
We study applications of divisibility properties of recurrence sequences to Tate’s theory of abelian varieties over finite fields.
We discuss an example of an open subset of a torus which admits a dense entire curve, but no dense Brody curve.
To any finite covering of degree between smooth complex projective manifolds, one associates a vector bundle of rank on whose total space contains . It is known that is ample when is a projective space ([Lazarsfeld 1980]), a Grassmannian ([Manivel 1997]), or a Lagrangian Grassmannian ([Kim Maniel 1999]). We show an analogous result when is a simple abelian variety and does not factor through any nontrivial isogeny . This result is obtained by showing that is -regular in the...
