炎热和风景,

The heat and the landscape I

Balint Virag

摘要:

1+1维随机环境中的热流在标度到由有向景观描述的随机几何之后收敛。在第一部分中,我们证明了O 'Connell-Yor聚合物和KPZ方程收敛于KPZ不动点。关键是一维Baik-Ben Arous-Peche统计量刻画了KPZ不动点。这产生了一个一般的和基本的方法,显示收敛的基础上建立的极限定理。Quastel和Sharkar在同一时间和地点独立地给出了KPZ收敛的一个无关证明。这些方法在不同的方向上进行了扩展:我们的方法扩展到聚合物模型,而他们的方法扩展到相互作用的粒子系统。

英文摘要:

Heat flows in 1+1 dimensional stochastic environment converge after scaling to the random geometry described by the directed landscape. In this first part, we show that the O'Connell-Yor polymer and the KPZ equation converge to the KPZ fixed point. The key is that one-dimensional Baik-Ben Arous-Peche statistics characterize the KPZ fixed point. This yields a general and elementary method that shows convergence based on previously established limit theorems. Independently, at the same time and place Quastel and Sharkar gave an unrelated proof of KPZ convergence. The methods invite extensions in different directions: ours to polymer models, and theirs to interacting particle systems.
