Sigma Models on Riemann Surfaces @alexarvanitakis I don't think that works. In that case the target space is $S^1\times \mathbf{R}^{25}$, which is a quotient of $\mathbf{R}^{26}$. The target space that I have in mind isn't a quotient of the plane. |

Sigma Models on Riemann Surfaces @Qmechanic thanks for the suggestion, I didn't have any specific literature in mind; I guess I just meant literature in the broader sense. |

Complex coordinates in CFT Maybe you're thinking about the fact that if you had a chiral boson like $\phi(z)$, then it transforms as $\phi'(f(z))=\phi(z)$, so it doesn't see the antiholomorphic side. There are also these warped CFTs, as considered by Hofman+Strominger, where the scaling only acts on the left-movers. By the way, you just confused everyone working in the cubicles around me at a grad school that will remain unnamed. |

Complex coordinates in CFT Sorry, I think we had overlapping edits... my last paragraph should answer your #1. For #2, it's true that $L_m$ and $\tilde{L}_m$ are independent, but in the end $\delta X$ only involves a certain linear combination of $L_m$ and $\tilde{L}_m$. |
