On the convergence to a statistical equilibrium for the wave equations coupled to a particle

T. V. Dudnikova

摘要:

考虑由经典粒子和标量场组成的线性哈密顿系统,该系统由变系数的波动方程或Klein-Gordon方程描述。系统的初始数据被假定为具有混合性质的随机函数。研究了随机解在时刻t \in \R的分布μ t.主要结果是μ_t收敛到高斯概率测度t \to \infty .研究了极限测度的混合性质。给出了Gibbs初始测度情形的应用。

英文摘要:

We consider a linear Hamiltonian system consisting of a classical particle and a scalar field describing by the wave or Klein-Gordon equations with variable coefficients. The initial data of the system are supposed to be a random function which has some mixing properties. We study the distribution μ_t of the random solution at time moments t\in\R. The main result is the convergence of μ_t to a Gaussian probability measure as t\to\infty. The mixing properties of the limit measures are studied. The application to the case of Gibbs initial measures is given.
