Model theoretic algebra has witnessed remarkable progress in the last few years. It has found profound applications in other areas of mathematics, notably in algebraic geometry and in singularity theory.
Since Wilkie's results on the ominimality of the expansion of the reals by the exponential function, and most recently even by all Pfaffian functions, the study of ominimal expansions of the reals has become a fascinating topic. The quest for analogies between the semialgebraic case and the ominimal case has set a direction to this research.
Through the ArtinSchreier Theory of real closed fields, the structure of the nonarchimedean models in the semialgebraic case is well understood. For the ominimal case, so far there has been no systematic study of the nonarchimedean models. The goal of this monograph is to serve this purpose.
The author presents a detailed description of the nonarchimedean models of the elementary theory of certain ominimal expansions of the reals in which the exponential function is definable. The example of exponential Hardy fields is worked out with particular emphasis. The basic tool is valuation theory, and a sufficient amount of background material on orderings and valuations is presented for the convenience of the reader.ReadershipGraduate students and research mathematicians interested in algebra, analysis, and model theory.

Reviews

This book is clearly and carefully written, … it would be a useful addition to the library of anyone interested in algebraic model theory, valuation theory, or general exponentiation.
Mathematical Reviews 
This book can easily be read by those with little or no background in ordered structures or valuation theory … the author has taken great care to include all the necessary material. Throughout, the presentation is wellmotivated, and the discussion and proofs are clear and thorough. For those unfamiliar with ordered fields, this book will serve as a pleasant introduction to the subject. And for those already familiar with the subject, it is gratifying to see that the author has successfully dealt with the intriguing challenge of using the structure theory to describe the implications of the presence of an exponential function.
