I am a post-doc in theoretical physics, interested mostly in high-energy physics and string theory. My main interest in mathematics comes from applications of geometry to physics, and especially Calabi-Yau spaces in string theory. I have a 'working knowledge' of algebraic and differential geometry.

How do I check whether an orbifold admits deformations? I'm just interested in deformations of these as varieties, so I'm not sure what you mean by 'deform the group action'. In the du Val examples, the smoothed varieties are not orbit spaces. |

Factoriality: local or global? Thank-you Angelo, that's very concise. |

Factoriality: local or global? "...analytic local ring, is not a UFD but the local ring itself is." This must be closely related to the fact that small resolutions always exist in the analytic category, but not in the algebraic category? Francesco, thank-you for your useful comments and the links. |

Smoothing of a hyperquotient singularity I see what you mean, but that seems strange: the smooth fibres are exactly the same as those for the deformations of the 'upstairs' geometry. |
