Many theorists examine the behavior of stock prices, and the random walk hypothesis attempts to explain why stocks move the way they do. The random walk hypothesis states that stock market prices ...

Random walks and percolation theory form a fundamental confluence in modern statistical physics and probability theory. Random walks describe the seemingly erratic movement of particles or entities, ...

The dynamics of many natural and artificial systems are well described as random walks on a network: the stochastic behaviour of molecules, traffic patterns on the internet, fluctuations in stock ...

We study the asymptotic behavior of a multidimensional random walk in a general cone. We find the tail asymptotics for the exit time and prove integral and local limit theorems for a random walk ...

We study limit laws for simple random walks on supercritical long-range percolation clusters on ℤ d , d ≥ 1. For the long range percolation model, the probability that two vertices x, y are connected ...

"A Random Walk Down Wall Street" is an influential stock market and investing related book written by Burton Malkiel, a leading economist, professor and former director of the Vanguard group and ...

An investment theory which claims the financial markets move up and down at random. Investors subscribing to the theory believe that historical price movements and trends provide no indication of ...

These are not the kinds of objects that concern Scott Sheffield. Sheffield, a professor of mathematics at the Massachusetts Institute of Technology, studies shapes that are constructed by random ...

Why is it that when you walk randomly, the more you walk, the farther you get from your starting point? The Quanta Newsletter ...
