Streets–Tian–Fino–Vezzoni intersection conjecture

About 2 years old · traced to

Let MM be a compact complex manifold. A Hermitian-symplectic metric is a Hermitian metric whose Kähler form is the (1,1)(1,1)-part of a closed 22-form. A balanced metric is a Hermitian metric whose Kähler form ω\omega satisfies d(ωn−1)=0d(\omega^{n-1})=0 on a complex manifold of dimension nn.

Streets–Tian–Fino–Vezzoni intersection conjecture. If MM admits a Hermitian-symplectic metric and a balanced metric, then it must admit a Kähler metric.

This is the intersection of the Streets–Tian and Fino–Vezzoni conjectures. The paper states that it remains open to the authors' knowledge.
