Fundamental form of a Hermitian manifold ($\omega$)

For the underlying Riemannian metric $g$ and complex structure $J$, the fundamental form is $\omega (u,v)=g(Ju,v)$. It is a real (1, 1)-form. In complex dimension $n$, the compatible orientation has Riemannian volume form ${\omega }^n/n!$, and its Hodge star operator satisfies

In an adapted real orthonormal coframe, the fundamental form of a Hermitian manifold is $\omega ={\sum }_j{e}^j\wedge f^j$ and the Riemannian volume form is ${\omega }^n/n!$. The complex-linear Hodge star sends each summand to the product of all the other oriented two-dimensional factors. Summation gives the displayed formula, valid for every Hermitian manifold, without a Kähler assumption.
