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