Witten Laplacian Methods for the Decay of Correlations
摘要:
本文的目的是将直接方法应用于研究自然出现在统计力学和欧几里得场论中的积分。我们提供加权估计导致指数衰减的两点关联函数某些经典的凸无界模型。该方法涉及与系统的哈密顿量相关的Witten Laplacian方程的解的研究。
英文摘要:
The aim of this paper is to apply direct methods to the study of integrals that appear naturally in Statistical Mechanics and Euclidean Field Theory. We provide weighted estimates leading to the exponential decay of the two-point correlation functions for certain classical convex unbounded models. The methods involve the study of the solutions of the Witten Laplacian equations associated with the Hamiltonian of the system.
