中间无序区域中有向聚合物的普适性

Universality of directed polymers in the intermediate disorder regime

Julian Ransford

AI总结:

本文证明了Krishnan和Quastel关于一般独立同分布权重有向聚合物在中间无序区域涨落收敛于Tracy--Widom GUE分布的猜想,对任意1/5<α<1/4成立。

摘要:

2018年,Krishnan和Quastel证明了在中间无序区域中,Seppäläinen的对数伽马聚合物的涨落在法律上收敛于Tracy--Widom GUE分布,该区域对应于取逆温度$β$依赖于聚合物长度$2n$,其中$β=n^{-α}$,且$α<1/4$。他们还猜想这一结果应适用于具有一般独立同分布权重的有向聚合物。我们证明了他们的猜想对任意$1/5<α<1/4$成立。

英文摘要:

In 2018, Krishnan and Quastel showed that the fluctuations of Seppäläinen's log-gamma polymer converge in law to the Tracy--Widom GUE distribution in the intermediate disorder regime, which corresponds to taking the inverse temperature $β$ to depend on the length of the polymer $2n$, with $β=n^{-α}$ for some $α<1/4$. They also conjectured that this should hold for directed polymers with general i.i.d weights. We prove that their conjecture is true for any $1/5<α<1/4$.
