Principal part of a meromorphic section
ID: principal-part-of-a-meromorphic-section
For a holomorphic line bundle on a complex curve, a meromorphic section modulo sections holomorphic through a point is its principal part. In a local coordinate and holomorphic local frame it is represented by finitely many negative powers. A vanishing permits prescribed principal parts, by a cutoff followed by solving a global Dolbeault operator equation.
