摘要:

跃迁函数为理解随机系统在相空间中不同区域间跃迁提供了有用信息。本文开发了一种点云离散化方法,用于数值计算跃迁函数,假设跃迁发生在潜在高维配置空间中的内在低维流形上。模型系统的数值示例验证了所提方法的有效性。

英文摘要:

The committor functions provide useful information to the understanding of transitions of a stochastic system between disjoint regions in phase space. In this work, we develop a point cloud discretization for Fokker-Planck operators to numerically calculate the committor function, with the assumption that the transition occurs on an intrinsically low-dimensional manifold in the ambient potentially high dimensional configurational space of the stochastic system. Numerical examples on model systems validate the effectiveness of the proposed method.
