Constructive Analysis (Grundlehren der mathematischen Wissenschaften, 279) by E. Bishop (PDF)

Description

This work grew out of Errett Bishop’s fundamental treatise ‘Founda­ tions of Constructive Analysis’ (FCA), which appeared in 1967 and which contained the bountiful harvest of a remarkably short period of research by its author. Truly, FCA was an exceptional book, not only because of the quantity of original material it contained, but also as a demonstration of the practicability of a program which most ma­ thematicians believed impossible to carry out. Errett’s book went out of print shortly after its publication, and no second edition was produced by its publishers. Some years later, ‘by a set of curious chances’, it was agreed that a new edition of FCA would be published by Springer Verlag, the revision being carried out by me under Errett’s supervision; at the same time, Errett gener­ ously insisted that I become a joint author. The revision turned out to be much more substantial than we had anticipated, and took longer than we would have wished. Indeed, tragically, Errett died before the work was completed. The present book is the result of our efforts. Although substantially based on FCA, it contains so much new material, and such full revision and expansion of the old, that it is essentially a new book. For this reason, and also to preserve the integrity of the original, I decided to give our joint work a title of its own. Most of the new material outside Chapter 5 originated with Errett.

⭐I’ve read a fair handful of Springer ‘yellow’ books (or parts, or tried to), and another handful of varied mathematical logics, and this falls comfortably into the intersection. I’ve used applied math books across other ranges of topics, too. But never, in any that I remember, did the opening chapter identify itself as “Manifesto.”Proofs in ‘formal’ logic can proceed as a purely textual exercise on the form of the statement, carried out as a series of string substitutions following rigorous rules – as Goedel observed to so many people’s dismay. A “there exists” statement can stand with no particular thought given to what it is that exists or how to find it. That’s where constructivism takes the road less traveled: If you can’t showed a specific example (or construction) of , you haven’t proved it exists. For example, “x not equal to y” surely means that “x > y” or “x < y". It's got to be one or the other, right? But, in constructivist-land, that's not good enough. If you want you say ("x > y) | (x < y)" you must show (or give construction to show) which of the two conditions is true. And do it again and again for every different x and y. And when defining a real number as an infinite series of other numbers, this seems to enclose the can of worms in an infinitely larger can. (For each number in that infinite series, what infinite series do you choose as its definition?}I'm not a mathematician, but a math user. I'm not a logician, but appreciate a range of approaches and levels of distinction. I came to this with high hopes, guided by another work's bibliography. I first heard of constructivism as a passing comment when I was a teenager (yes, that kind of teenager), and didn't think much about it. Now, much later, I come at it again and don't think much of it. Math, as art, has its fine and abstract art, but also its commercial and applied art. In the art world, there's a snobby distinction between the two. I'm not enough of a mathematician to have experienced such distinction, but I'm sure it's there. I'm a practitioner - versatile, I like to think - but not one to appreciate the most delicate nuances. For anyone who does appreciate them, I wish you all the very best.-- wiredweird ⭐As someone interested in mathematical modeling, I found this book a refreshing relief from the mystical, if not illogical methods of most of academic mathematics. True, I did run into a few brick walls, but I also did not take the time to study everything critically. My attitude is that the academics are supposed to keep people like me honest, not the other way around. Of course, they have failed miserably with the physicists. An obvious clarification that Bishop and Bridges did not employ was the fact that classification is much more complex and subjective than counting. That is the problem with using set theory as a foundation for mathematics and then attempting to clean up the mess ex post facto. Sets are useful, when carefully deployed, to create constructs like function spaces, which can lead to potent methodologies, such as the Picard-Chebyshev ODE solver. Scientists and engineers, and God willing, even mathematicians, should become mathematically literate, as well as computationally competent. What has been long needed is a good undergraduate text, and here it is:
