A/2 model classical correlation functions
For Xcompact, we have n ψ+
ı zero modes and
r λ a zero modes:
〈O 1 · · · O m 〉 =
∫
X
Selection rule:
H q 1
(X, Λ p 1
E ∨ ) ∧ · · · ∧ H q m
(X, Λ p m
E ∨ )
∑
i q ∑
i = n,
i p i = r
〈O 1 · · · O m 〉 ∼ ∫ X Htop (X, Λ top E ∨ )
The constraint Λ top E ∨ ∼ = K X
makes the integrand a top-form.
