AI中文摘要：
我们从库仑气体表示出发，发展了Toda场论关联函数的一种概率构造。将初级场的$n$点函数重新解释为关于高斯测度的随机变量的$w$矩，我们推导出对Toda动量和耦合常数的约束。推导了相关随机变量的$L^2$和$L^p$收敛条件、关联函数的平凡性约束以及交叉矩的局部可积性条件。这些约束定义了Toda关联函数的一个扩展收敛区域，并为Seiberg界提供了系统的概率解释。我们进而通过采用随机变量的Mellin-Barnes表示来解析延拓矩指标。局部收敛边界变为亚纯的局部可积性因子，在$b\ o0$的半经典极限下，这些因子重构了Liouville电荷极点格。对于$A_n$ Toda理论，我们证明了在该半经典极限下，自然的$W_n$-闭包条件在完整Toda理论内部选择了秩一的、类Virasoro的子模。在这些切片上，标量可积性条件约化为类Liouville因子，并恢复了相应的Toda电荷极点格。
英文摘要：
We develop a probabilistic construction of Toda field theory correlators from the Coulomb gas representation. Reinterpreting $n$-point functions of primaries as $w$-moments of random variables with respect to a Gaussian measure, we derive constraints on the Toda momenta and coupling constant. $L^2$ and $L^p$ convergence conditions for the associated random variables, triviality constraints on the correlators, and local integrability conditions for the cross-moments are derived. These constraints define an extended region of convergence for the Toda correlators and provide a systematic, probabilistic interpretation of the Seiberg bounds. We proceed to analytically continue the moment indices by employing a Mellin-Barnes representation of the random variables. The local convergence boundaries become meromorphic local integrability divisors, and, in the semiclassical $b\to0$ limit, these divisors reconstruct the Liouville charge pole lattice. For $A_n$ Toda theory, we show that natural $W_n$-closure conditions in this semiclassical limit select rank-one, Virasoro-like submodules inside the full Toda theory. On these slices, the scalar integrability conditions reduce to Liouville-like divisors and recover the corresponding Toda charge pole lattices.
