Abstract: In this talk, we shall use the concept of RC-positivity to
investigate the existence of scalar-flat Hermitian metrics on ruled
manifolds and prove that a ruled surface X has a scalar-flat
Hermitian metric if and only if the curve genus g is greater than
one and m(X)>2-2g where m(X) is an intrinsic number depends
on the complex structure of X.
