A holomorphic differential form of degree on a complex manifold
is a bundle section of the bundle
whose coefficient functions in every holomorphic coordinate chart are holomorphic
functions. The bundle
is the
th exterior power of the
holomorphic cotangent bundle. Such a bundle
section is also called a holomorphic
-form. In local holomorphic coordinates
,
...,
,
it is a sum of terms
where the coefficients are holomorphic
functions.
