1. Introduction and overview
The Liouville CFT onCg,ndescribes theUV regionof the gauge theory, and the Seiberg-Witten (Gaiotto) curveCSWis obtained as aramified double coverofCg,n.

We introduce mass scale~as1=b~,2=b−1~, and rescaled a,mi as a→a/~,mi →mi/~, and then the SW curveCSWis obtained from the “semiclassical limit”1,2a,mi of thestress tensor T(z):
hT(z)Vm2(q)Vm1(1)i{a}∼ − 1
~2φSW(z)hVm2(q)Vm1(1)i{a}, where Vm(z) =exp(2mφ(z))is the primary operator with conformal weight∆m=m(Q−m), (Q=b+b−1).
Above discussion can be generalized toasymptotically free theory. In the case, on the CFT side“irregular” state (Gaiotto state) “|Gi”is introduced. −→Section 2

Therefore the subleading termW(ai,z)is obtained as the Abel-Jacobi map on the SW curveCSW.
In sectiron 3, higher order terms are discussed by theEynard-Orantin topological recursion relationon SW curve.

By taking an appropriate local coordinate patch whose parameterx represents the open string modulix =exp(−c+i∫
S1A), we obtain a mirror curve which describes the moduli of thetoric brane:
Cmirror={x,y ∈ C∗ |H(x,y) =0} ⊂ C∗× C∗.
By the mirror maps:
Tα(z) = I
Aα
λmirror(x) = I
Aα
log y(x)dx

λmirror(x), the B-model is related to the A-model.

In the previous discussion Recursion , by replacingλSW(z)with λmirror(x) :=log y(x)dx
x ,
we define thefree energiesFmirror(g,h). And thenBKMP conjecturestates:
Fmirror(g,h)(x1, . . . ,xh) =FA(g,h)(X1, . . . ,Xh).
In this equality the (open & closed) mirror maps are used, and the A-model free energiesFA(g,h)are computed by thetopological vertex.

We insert a toric brane on an inner leg of local F0. Relation of the parameters is
