The statistics of rare events, the so-called black-swan events, is governed by non-Gaussian distributions with heavy power-like tails. We calculate the Green functions of the associated Fokker-Planck equations and solve the related stochastic differential equations. We also discuss the subject in the framework of path integration.
稀有事件(即所谓的黑天鹅事件)的统计由具有重幂律尾的非高斯分布所支配。我们计算相关福克 - 普朗克方程的格林函数,并求解相关的随机微分方程。我们还在路径积分的框架内讨论这个主题。
