我们为二维相互作用粒子系统的大族引入了循环(或戴森-施温格)方程的动态版本,包括戴森布朗运动、非相交伯努利/泊松随机游走、$eta$-角过程、Gelfand-Tsetlin 模式上的均匀和 Jack 变形测度、Macdonald 过程以及菱形平铺上的 $(q,kappa)$ 分布。在技​​术假设下,我们表明动态环方程会导致高斯场类型波动。作为一个应用,我们计算菱形平铺上 $(q,kappa)$ 分布的极限形状,并证明它们的高度波动以适当的复杂结构收敛到高斯自由场。
We introduce dynamical versions of loop (or Dyson-Schwinger) equations for large families of two--dimensional interacting particle systems, including Dyson Brownian motion, Nonintersecting Bernoulli/Poisson random walks, $eta$--corners processes, uniform and Jack-deformed measures on Gelfand-Tsetlin patterns, Macdonald processes, and $(q,kappa)$-distributions on lozenge tilings. Under technical assumptions, we show that the dynamical loop equations lead to Gaussian field type fluctuations. As an application, we compute the limit shape for $(q,kappa)$--distributions on lozenge tilings and prove that their height fluctuations converge to the Gaussian Free Field in an appropriate complex structure.
