Random Walk: A Modern Introduction

An advanced treatment of random walks written for students and researchers in probability and related fields.

A random walk is one of the most studied topics in probability theory and has many important applications outside of mathematics. Ideal for graduate students, this text develops the theory from basic definitions through to current research problems. It is also suitable for mathematicians working in related fields.Random walks are stochastic processes formed by successive summation of independent, identically distributed random variables and are one of the most studied topics in probability theory. This contemporary introduction evolved from courses taught at Cornell University and the University of Chicago by the first author, who is one of the most highly regarded researchers in the field of stochastic processes. This text meets the need for a modern reference to the detailed properties of an important class of random walks on the integer lattice. It is suitable for probabilists, mathematicians working in related fields, and for researchers in other disciplines who use random walks in modeling.
