Groups and random walks

Random walks, the process of partial sums of sequences of independent identically distributed random variables, are classical objects in probability theory and one of the main focuses in the work of Kai-Lai Chung during his time at Cornell around 1950. Fourier analysis is the classical tool of choice in this subject.
