Generalised <strong>orbifolds</strong><br />
Theorem.<br />
A = X † ⊗ X is a symmetric Frobenius algebra for any 1-morphism X in B.<br />
If dim(X) is invertible (easy to check for B = LG) then:<br />
A = X † ⊗ X is a special symmetric Frobenius algebra.<br />
X ⊗A X † ∼ = I.<br />
X <strong>and</strong> X † are mutually inverse in Borb.<br />
