Twisted constant scalar curvature Kähler metrics and Kähler slope stability
Twisted constant scalar curvature Kähler metrics and Kähler slope stability
On a compact Kähler manifold we introduce a cohomological obstruction to the solvability of the constant scalar curvature (cscK) equation twisted by a semipositive form, appearing in works of Fine and Song-Tian. As a special case we find an obstruction for a manifold to be the base of a holomorphic …
