中文摘要
数学中对随机游动的研究至少可以追溯到波利亚在1921年的工作;他证明了一维或二维上的简单随机游动将无限地返回到起点,而在三维或更多维度上,它最终将离开最初的邻域,永远不会回来。在大尺度下,随机游动可以用布朗运动来近似。扩散和偏微分方程(PDE)之间的联系源于爱因斯坦;扩散过程的转移概率是热方程的解。这些联系具有很大的普遍性,在20世纪下半叶,数学家们对它们进行了非常彻底的探索。
英文摘要
The study of random walks in mathematics goes back as least as far as the work of Polya in 1921; he showed that a simple random walk in one or two dimensions will return to its starting point infinitely often, while in 3 or more dimensions it will ultimately leave its initial neighbourhood, never to return. At large length scales random walks can be approximated by Brownian motion. The connection between diffusion and partial differential equations (PDE) is due to Einstein; the transition probabilities of the diffusion process are solutions to the heat equation. These connections, which hold in great generality, were explored very thoroughly in the second part of the 20th century by mathematicians.
