A central study in Probability Theory is the behavior of fluctuation phenomena of partial sums of different types of random variable. One of the most useful concepts for this purpose is that of the random walk which has applications in many areas, particularly in statistical physics and statistical chemistry.
Originally published in 1991, Intersections of Random Walks focuses on and explores a number of problems dealing primarily with the nonintersection of random walks and the self-avoiding walk. Many of these problems arise in studying statistical physics and other critical phenomena. Topics include: discrete harmonic measure, including an introduction to diffusion limited aggregation (DLA); the probability that independent random walks do not intersect; and properties of walks without self-intersections.
The present softcover reprint makes this classic monograph available to a wider audience and includes corrections and an addendum from the second printing (1996). With the inclusion of a self-contained introduction to the properties of simple random walk, and an emphasis on rigorous results, the book will be of use to researchers in probability and statistical physics and to graduate students interested in basic properties of random walk.
