Lin Tongling, Pujos Cyril, Ou Congjie, Bi Wenping, Calvayrac Florent, Wang Qiuping A

摘要:

本文是关于保守哈密顿系统或弱阻尼布朗粒子随机运动的数值实验。目标是证明路径概率的存在性并计算其值。通过观察大量粒子在高斯噪声和保守力作用下从一点运动到另一点,确定了路径概率随沿路径的作用呈指数下降。

英文摘要:

This work is a numerical experiment of stochastic motion of conservative Hamiltonian system or weakly damped Brownian particles. The objective is to prove the existence of path probability and to compute its values. By observing a large number of particles moving from one point to another under Gaussian noise and conservative forces, it is determined that the path probability decreases exponentially with action along the paths.
