The book develops modern methods and in particular the "generic
chaining" to bound stochastic processes. This methods allows in
particular to get optimal bounds for Gaussian and Bernoulli processes.
Applications are given to stable processes, infinitely divisible
processes, matching theorems, the convergence of random Fourier series,
of orthogonal series, and to functional analysis. The complete solution
of a number of classical problems is given in complete detail, and an
ambitious program for future research is laid out.
