Existence of a cohomologous k-positive form satisfying the subsolution inequality

Let MM be a compact Hermitian manifold of complex dimension nn, let

beafixedHermitianform,andletbe a fixed Hermitian form, and let

be a closed kk-positive form. Let cc be the constant appearing in the equation and let pp range over the integers nl,,n1n-l,\ldots,n-1. A subvariety VewlinesubseteqMV ewline subseteq M of dimension pp is integrated against the indicated (p,p)(p,p)-form.

Geometric subsolution conjecture. There exists a kk-positive form  in []'\text{ in }[] satisfying the inequality from the paper with ' in place of

if and only if, for every subvariety $V ewline \subseteq M$ of dimension $p=n-l,\text{... }n-1$,

\int_V c\frac{k!}{(k-n+p)!} \chi^{k-n+p}\wedge \alpha^{n-k}-\frac{l!}{(l-n+p)!} \chi^{l-n+p}\wedge \alpha^{n-l}>0.

ThisisproposedasageometriccriterionensuringtheexistenceofaThis is proposed as a geometric criterion ensuring the existence of a

-subsolution, in analogy with the cited conjecture for the case k=nk=n, l=n1l=n-1; its resolution is not established in the supplied text.
