General decomposition<br />
conjecture<br />
Consider [X/H] where<br />
1 −→ G −→ H −→ K −→ 1<br />
gerbe<br />
and G acts trivially.<br />
We now believe, for (2,2) CFT’s,<br />
CFT([X/H]) = CFT<br />
([<br />
(X × Ĝ)/K<br />
])<br />

union <strong>of</strong><br />
spaces<br />
(together with some B field), where<br />
Ĝ is the set <strong>of</strong> irreps <strong>of</strong> G
