摘要

本文给出了以下性质间的关系:(a) 构型空间Υ{\boldsymbol\Upsilon}上概率测度μ\mu的尾平凡性;(b) L2L^2-运输型距离dˉΥ\bar{\mathsf d}_{{\boldsymbol\Upsilon}}的有限性;(c) Υ{\boldsymbol\Upsilon}μ\mu-对称Dirichlet型的不可约性。作为应用,我们获得了具有由行列式/积行列式点过程(包括sine2\mathrm{sine}_{2}Airy2\mathrm{Airy}_{2}Besselα,2\mathrm{Bessel}_{\alpha, 2}α1\alpha \ge 1)及Ginibre\mathrm{Ginibre}点过程)产生的对数相互作用的相互作用无穷扩散的遍历性(即收敛到平衡),特别地,涵盖了无标号Dyson布朗运动的情形。证明中,Ghosh--Peres意义下点过程的数刚性起到了关键作用。

备注

35 pages, The choice of cores of Dirichlet forms is made flexible and not necessarily to be cylinder functions now. A new proof of the main result (Theorem I) does not rely on the Sobolev-to-Lipschitz property (SL), so that the description of (SL) is deleted. The base space is restricted to be the Euclidean space for the sake of simplicity. The transportation distance is modified to be a variant
