= Normal bundle of a linear complex-projective embedding

Near a projective subspace, transverse directions are linear maps from the tautological line to the complementary coordinate vector space. This describes the actual complex <normal bundle>. The conjugate line and the dual line are complex-isomorphic using a <Hermitian metric>; neither is the original tautological line as a complex bundle in general.
