ag.algebraic geometry - Transition Functions and Complex Structure

For a real manifold MM the transition functions of the tangent bundle T(M)T(M) come from the Jacobian of the change-of-coordinate maps.



When MM is complex, it has a complex tangent bundle TmathbbCMTmathbbCM, which can be identified with the holomorphic vector bundle T(1,0)subsetTMotimesmathbbCT(1,0)subsetTMotimesmathbbC. The transition functions on TmathbbCMTmathbbCM are given by the (complex) Jacobian of the change-of-coordinate maps, so the same is true for T(1,0)T(1,0).



Since T(0,1)T(0,1) is the complex conjugate bundle, its transition functions are the complex conjugate of the same Jacobian.
