Foundations of constructive probability theory Using Bishops work on constructive analysis as a framework this monograph gives a systematic detailed and general constructive theory of probability theory and stochastic processes. It is the first extended account of this theory: almost all of the constructive existence and continuity theorems that permeate the book are original. It also contains results and methods hitherto unknown in the constructive and nonconstructive settings. The text features logic only in the common sense and beyond a certain mathematical maturity requires no prior training in either constructive mathematics or probability theory. It will thus be accessible and of interest both to probabilists interested in the foundations of their speciality and to constructive mathematicians who wish to see Bishops theory applied to a particular field
