Imagine a particle that travels along the line in the following way: At each moment of time the particle decides randomly (and independently of the past) whether to jump to the left or to the right. Mathematicians would call this simple model a "discrete time random walk". A natural generalization of this model to continuous time would be called a "one-dimensional Levy process".

想象一个粒子以下列方式沿着这条线行进：在每个时刻，粒子随机地（并且与过去无关）决定是跳到左边还是右边。数学家将这个简单的模型称为“离散时间随机游走”。该模型对连续时间的自然推广将被称为“一维 Levy 过程”。
