Preface
This monograph, based on the author’s 1997 EMS Lectures given at the University of Helsinki in May/June 1997, outlines the Loeb measure construction (a way to construct rich measure spaces using Robinson’s nonstandard analysis) and discusses recent applications in stochastic fluid mechanics, stochastic calculus of variations (“Malliavin calculus” and related topics), and mathematical finance theory. The four lectures in Helsinki were designed for a general audience, as is the expanded version presented here. No previous knowledge of either nonstandard analysis or the fields of application is assumed, beyond the general knowledge of the working mathematician. The aim in Chapter 1 is to provide a brief but coherent account of the fundamentals of nonstandard analysis (NSA) and the Loeb construction that is sufficient to make sense of the applications of the later chapters. For each of these we have endeavoured to provide sufficient by way of introduction to the topics concerned to enable even the reader unfamiliar with them to appreciate the basic ideas of the field and then the particular contributions that can be made using NSA and Loeb measures. In fact, one of the major contributions that NSA has made to many fields of application is to aid in understanding of the basic ideas of that field
