Meaning in context

A smooth map from a Riemann surface with complex structure j to a smooth manifold with almost complex structure J whose differential intertwines those structures, so du composed with j equals J composed with du.

从复结构为 jj 的黎曼曲面到近复结构为 JJ 的光滑流形的光滑映射 uu,满足 du∘j=J∘dudu\circ j=J\circ du。

Example

For the usual structures on C\mathbb C, u(z)=z2u(z)=z^2 is pseudoholomorphic; u(z)=z‾u(z)=\overline z is not, since its differential anticommutes with multiplication by ii.

Usage and distinctions

The word curve denotes a parametrized map, not just its image. The map need not be embedded or immersive; branch points and constant maps are allowed by this definition.
