The subject of real analytic functions is one of the oldest in mathematical analysis. Today it is encountered early in one's mathematical training： the first taste usually comes rn calculus. While most working mathematicians use real analytic functions from time to time in their WOfk， the vast lore of real analytic functions remains obscure and buried in the literature. It is remarkable that the most accessible treatment of Puiseux's thcorem is in Lefschetz's quute old Algebraic Geometry， that the clearest discussion of resolution of singularities for real analytic manifolds is in a book review by Michael Atiyah， that there is no compre hensive discussion in print of the embedding problem for real analytic manifolds.
　　We have had occasion in our collaborative research to become acquainted with both the history and the scope of the theory of real analytic functions. It seems both appropriate and timely for us to gather together this information in a single volume. The material presented here is of three kinds. The elementary topics， covered in Chapter 1， are presented in great detail. Even results like a real analytic inverse function theorem are difficult to find in the literature， and we take pains here to present such topics carefully. Topics of middling difficulty， such as separate real analyticity， Puiseux series， the FBI transform， and related ideas （Chapters 2-4）， are covered thoroughly but rather more briskly. Finally there are some truly deep and difficult topics： embedding of real analytic manifolds， sub and semi-analytic sets， the structure theorem for real analytic varieties， and resolution of singularities are disc，ussed and described. But thorough proofs in these areas could not possibly be provided in a volume of modest length.
