在本文中,我们证明了一个布朗吉布斯线系综完全由其顶部曲线的有限维边缘分布所刻画,即其顶部曲线的有限维集合构成一个分离类。我们这一结果的一个特别推论是,艾里线系综是唯一的布朗吉布斯线系综,其顶部曲线为艾里₂过程。
In this paper we show that a Brownian Gibbsian line ensemble is completely characterized by the finite-dimensional marginals of its top curve, i.e. the finite-dimensional sets of the its top curve form a separating class. A particular consequence of our result is that the Airy line ensemble is the unique Brownian Gibbsian line ensemble, whose top curve is the Airy$_2$ process.
