自相互作用Wiener路的Gibbs测度

Gibbs measures for self-interacting Wiener paths

M. Gubinelli

摘要:

本文研究了$d$维Wiener测度上的一类在路径一致平移下不变的规范。这种退化是通过限制措施的$σ$ -代数生成的坐标过程的增量。我们解决了吉布斯测度的存在性和唯一性问题,并证明了一个中心极限定理的重标增量。这些结果适用于研究量子粒子与标量玻色子场相互作用的Nelson模型的基态。

英文摘要:

In this note we study a class of specifications over $d$-dimensional Wiener measure which are invariant under uniform translation of the paths. This degeneracy is removed by restricting the measure to the $σ$-algebra generated by the increments of the coordinate process. We address the problem of existence and uniqueness of Gibbs measures and prove a central limit theorem for the rescaled increments. These results apply to the study of the ground state of the Nelson model of a quantum particle interacting with a scalar boson field.
