| 12 mins ago | comment | added | Balazs | This is likely to be subtle. Craw-Maclagan-Thomas in arxiv.org/abs/math/0611840 constructed an example of a finite subgroup $G\subset GL(3)$ and a monomial equivariant ideal $J$ such that $[J] \in G$-Hilb does not lie on the "main" coherent component, so in particular $G$-Hilb is not irreducible. I am not sure about connectedness even in this example. | |
