"This book presents reverse mathematics to a general mathematical audience for the first time. Reverse mathematics is a new field that answers some old questions. In the two thousand years that mathematicians have been deriving theorems from axioms, it has often been asked: which axioms are needed to prove a given theorem? Only in the last two hundred years have some of these questions been answered, and only in the last forty years has a systematic approach been developed. In Reverse Mathematics, John Stillwell gives a representative view of this field, emphasizing basic analysis--finding the "right axioms" to prove fundamental theorems--and giving a novel approach to logic. Stillwell introduces reverse mathematics historically, describing the two developments that made reverse mathematics possible, both involving the idea of arithmetization. The first was the nineteenth-century project of arithmetizing analysis, which aimed to define all concepts of analysis in terms of natural numbers and sets of natural numbers. The second was the twentieth-century arithmetization of logic and computation. Thus arithmetic in some sense underlies analysis, logic, and computation. Reverse mathematics exploits this insight by viewing analysis as arithmetic extended by axioms about the existence of infinite sets. Remarkably, only a small number of axioms are needed for reverse mathematics, and, for each basic theorem of analysis, Stillwell finds the "right axiom" to prove it. By using a minimum of mathematical logic in a well-motivated way, Reverse Mathematics will engage advanced undergraduates and all mathematicians interested in the foundations of mathematics."-- Aucune description trouvée dans une bibliothèque |

It is an interesting approach to Analysis, but I don’t really know all that much about Mathematical Analysis. I never took it in school, since I only got up to Calculus II in college. Therefore, there are several things that I find annoying, but that is only because I wasn’t paying attention the first time through. For instance, there is a portion where ZF is mentioned and I didn’t know what that was. The book might use a lot of acronyms but it usually explains what they mean before the author dives into the gist. This is important for when Stillwell decides to drop stuff like ACA and WKL and other such ideas.
In writing this book, it is clear from the text that the author wanted to establish a solid foundation for analysis given some advances in Logic. This is mentioned in the text itself. It doesn’t have any problems to solve or questions to answer.
The book is quite interesting as I mentioned before. It is rather short, but it is densely packed with ideas. It doesn’t have a glossary, choosing instead to jump straight to the Bibliography and Index. In that sense, I could say that the author dropped the ball, but it is possible that the editor thought it unnecessary for the target audience. Then again, you could always search for what he means by using the Internet. (
