Boucksom-Demailly-P5un-Peternell duality conjecture for compact K4hler manifolds

Let XX be a compact K4hler manifold of complex dimension nn. The cone E\mathcal{E} of pseudoeffective classes consists of classes in HR1,1(X)H^{1,1}_{\mathbb{R}}(X) containing a closed positive current, and the movable cone M\mathcal{M} is the closed convex cone in HRn1,n1(X)H^{n-1,n-1}_{\mathbb{R}}(X) generated by classes

μ(β~1β~n1),\mu_*(\tilde{\beta}_1\wedge\cdots\wedge\tilde{\beta}_{n-1}),

where μ:X~X\mu:\tilde{X}\to X is a smooth modification and the β~i\tilde{\beta}_i are K4hler classes on X~\tilde{X}. The Poincar9 pairing is (αη)=Xαη(\alpha\cdot\eta)=\int_X\alpha\wedge\eta. Boucksom-Demailly-P5un-Peternell conjecture. On any compact K4hler manifold XX, the cones E\mathcal{E} and M\mathcal{M} are dual via the Poincar9 pairing of HR1,1(X)H^{1,1}_{\mathbb{R}}(X) with HRn1,n1(X)H^{n-1,n-1}_{\mathbb{R}}(X). Equivalently, a class αHR1,1(X)\alpha\in H^{1,1}_{\mathbb{R}}(X) contains a closed positive current exactly when it has nonnegative pairing with every class in M\mathcal{M}. This extends the projective-manifold duality theorem of Boucksom, Demailly, P5un and Peternell to the compact K4hler setting; the conjecture remains open in general.
