Download Free Mathematics Books by Knapp

From this page anyone can download free PDF files of  "digital second editions" of the four books of mine whose first editions were published in the Cornerstones series of Birkhäuser Boston between 2005 and 2007.  These books are at the first-year graduate level or a little higher, depending on one's university.  All four are available for download now:

The files of the books are being made available as a gift to the mathematics community worldwide.  The files are limited to noncommercial use for purposes of education, scholarship, and research.  Pages of the files may be freely stored electronically, freely accessed, freely copied, and freely transmitted.  A few specific conditions on electronic use are imposed to maintain the noncommercial nature of the files and ensure the integrity of the individual pages, including that no one is ever charged a fee for the acquiring or looking at the files and that the files are not translated into any other computer format (e.g., EPUB).  The specific conditions are spelled out on a separate webpage, and a copy of them appears on page iv (the fourth page of the front matter) of the PDF file of each book.  Please adhere to these conditions.

The books were typeset by Textures using AMS-TeX, and the figures were drawn in Mathematica.  Anyone who wants to know how a display was coded in AMS-TeX or a figure was drawn in Mathematica is invited to send the author an email and ask, rather than try to dissect the PDF files.  Most of each book is available in PDF/X compliant format on request.

Printing of the files is constrained legally.  The reason is that Springer has a stake in printed copies of these books, as is explained in the brief history below, and Springer's permission may be required for printing.  For a discussion of these legal considerations, click here.


Brief History

The author (Anthony W. Knapp) and the publisher (Birkhäuser Boston, Inc.) signed two contracts dated March 19 and 20, 2003, one for a book in real analysis and one for a book in algebra.  Under these contracts the author retained copyright but granted to the publisher a license for the "full and exclusive rights covered under the copyright of the Work and all revisions thereof .... ." The contracts specifically stated, "The rights granted and assigned to the Publisher are limited to those rights concerning print media."

For marketing purposes, each of the books was later subdivided into two smaller books, Basic and Advanced, which were printed separately.  The two real analysis books appeared in print in 2005, and the two algebra books appeared in print in 2006 and 2007.  No decision was made at that time concerning electronic publication.  Nevertheless, some companies and individuals took it upon themselves to publish and sell electronic versions of some or all of the books without permission; some of these electronic versions were of poor quality. 

Birkhäuser, a Swiss company, had been a member of the Springer group since 1985.  About 2010, Springer underwent some kind of reorganization, the Boston office of Birkhäuser was closed, and the operations of the Birkhäuser Boston office were consolidated into the New York office of Springer.  The contracts remained in force but with Springer as publisher rather than Birkhäuser.  Thus Springer as of 2016 has "full and exclusive rights covered under the copyright of the Work" concerning print media, for both the original editions and the current revisions.

Before 2016 the author never authorized anyone to publish any of the books in any form other than print media.  Now he is giving a general authorization concerning PDF files of the books, and he is hoping that people will not be tempted to degrade the quality of the files by translating them into other formats.


Front Matter of Each Book

Some people may prefer to know something about one or another book before downloading the entire book.  For that reason, links are provided here for downloading the front matter for each book.  In each case this includes page iv (the copyright page), the table of contents, the preface for the second edition, the preface for the first edition, and some other items.  The preface for the second edition tells what the new features are for each book.  It is not necessary to download the front matter if one is going to download the entire book from a link below.

Download Digital Second Editions

For each book the inside is available as a single PDF file, and the front cover is available as a JPG file.  Also the front cover and the inside are available together as a single PDF file.

The inside pages are black and white only.  The printed area of the inside pages is 28 picas wide and 43 picas high.  It is centered left to right, so that if two printed pages on pages of size 8.5 inches by 11 inches are held up back to back, then their printed areas will coincide.  The size of the front cover is 6 inches by 9.5 inches and the placement of the cover in the PDF files is consistent with the printing on the inside pages.  Thumbnails of the front covers appear below.
