Abstract: Hartshorne ampleness of vector bundles will be introduced and a generalization of a criterion (due to Schneider and Tancredi) to recognize ample bundles will be presented. This work is joint with Indranil Biswas. We shall also introduce differential-geometric positivity conditions and discuss PDE that are relevant for studying the Griffiths conjecture that asserts that Hartshorne ample bundles admit Griffiths positively curved metrics.
