For an arbitrary-rank vector bundle over a projective manifold, J.-P.
Demailly proposed several systems of equations of Hermitian-Yang-Mills type for
the curvature tensor to settle a conjecture of Griffiths on the equivalence of
Hartshorne ampleness and Griffiths positivity. In this article, we have studied
two proposed systems and proved that these equations have smooth solutions for
the Vortex bundle using the continuity method.Comment: 21 page
