 Laurent gluing of Dolbeault primitives on the projective line

For a smooth $(0,1)$-form on the complex projective line, solve its Dolbeault operator equation on a disc about zero and a disc about infinity. The difference of the primitives is a holomorphic function on their annular overlap. Split its Laurent series into a nonnegative-power part extending to the finite disc and a negative-power part extending holomorphically across infinity. Subtract the first part from the finite primitive and add the second to the infinite primitive. The results agree and define a global primitive, without Hodge theory.
