Remarks on toric manifolds whose Chern characters are positive

Algebraic Geometry 2019-12-10 v2

Abstract

We show that the second Chern character of any projective toric manifold of Picard number three is not ample. In connection with this result, we give various examples of the positivity of higher Chern characters of projective toric manifolds.
