受(2+1)维底层Solid-On-Solid(SOS)模型水平线条研究的启发,该研究针对盒子角落附近的情况,我们推导了来自(1+1)维SOS模型的K条曲线集合的极限定律,该模型带有面积倾斜,且位于{-N,…,N}中的楔形底层之上。我们证明存在显式临界点α₀=1>α₁>…>α_K>0,使得对于每个r≥1,在区间±(α_r N, α_{r-1} N)上,通过(N^(2/3), N^(1/3))缩放后的底部K+1-r条曲线,趋向于非交叉布朗路径的几何面积倾斜集合(Brownian GATE)的定律,且在这2K个区间间相互独立。所有其他经中心化并通过(N, √N)缩放后的曲线,趋向于K个合适布朗桥的乘积。

英文摘要

Motivated by the study of the level lines of the $(2+1)$D Solid-On-Solid (SOS) model above a floor, near the corners of the box, we derive the limit law of an ensemble of $K$ curves from a $(1+1)$D SOS model, with an area tilt, and above a wedge-shaped floor in $\{-N,\ldots,N\}$. We show that there exist explicit critical points $α_0=1>α_1>\ldots>α_K>0$ such that, for each $r \geq 1$, along the intervals $\pm(α_{r} N,α_{r-1} N)$, the bottom $K+1-r$ curves, rescaled by $(N^{2/3},N^{1/3})$, tend to the law of a Geometrically-Area-Tilted Ensemble of non-crossing Brownian paths (Brownian GATE), independently across those $2K$ intervals. All other curves, centered and rescaled by $(N,\sqrt{N})$, tend to a product of $K$ suitable Brownian bridges.
