Acknowledgment from
Index to Mathematical Problems 1980-1984
by Stanley Rabinowitz
The effort of many people went into producing this compendium. Their help is greatly appreciated. Data entry and proofreading were done by Selma Burrows, Mark Buxbaum, Michael Clarke, Anne R. Costa, Joan Duprey, Kathleen Duprey, Carol Anderson Peters, Stanley Rabinowitz, and Dennis Spellman. I could not have completed this monumental task without their help. In addition, I thank Cheryl Hoffman, Helen Metcalf, and Mindy Swartz who have joined in to help with work on future indexes. Special thanks to George and Roberta Berry who proofread most of the non-mathematical material and reviewed the design, layout, and composition of the text. My editorial board (George Berzsenyi, Clark Kimberling, Murray S. Klamkin, Leroy F. Meyers, and Jordan Tabov) did an exceptional job in reviewing all of the material from my many mailings. They offered good advice and were instrumental in the shaping of this index. Leroy Meyers was extremely helpful with many detailed comments, especially with respect to the proper spelling of people's names. I thank Murray Klamkin for his early encouragement and for agreeing to write the Foreword. Anne Costa did a fantastic job of reviewing the final manuscript. Problems were classified by Joan Duprey, Stanley Rabinowitz, and Dennis Spellman. A few problems had to be translated into English. For these and for the many problems that have been translated for future indexes, I thank George Berzsenyi, Leroy F. Meyers, Susan Oliver, Dennis Spellman, and Jordan Tabov. Special thanks to Mark Buxbaum who helped make the keyword index a reality, to Jim Ravan for his database expertise, and to Herb Jacobs for his help in many phases of the book production.
This index gives credit to the many authors of the problems indexed herein and also carefully cites the sources (names of the journals and page numbers) in which these problems were originally posed. Consult the Problem Chronology (page 299) to determine the original source for any problem listed herein. I wish to thank the following organizations for giving me permission to reprint their problems in this index:
The Mathematical Association of America (for The American Mathematical Monthly, Mathematics Magazine, The College Mathematics Journal), the American Mathematical Association of Two-Year Colleges (for The AMATYC Review), the MATYC Journal, Inc. (for Mathematics and Computer Education), the Canadian Mathematical Society (for Crux Mathematicorum, CMS Notes, and the Canadian Mathematical Bulletin), Birkhäuser-Verlag (for Elemente der Mathematik which will appear in a future volume), Springer-Verlag (for Abacus and The Mathematical Intelligencer), the Fibonacci Association (for The Fibonacci Quarterly), the Mathematical Association (for The Mathematical Gazette), Baywood Publishers (for the Journal of Recreational Mathematics), the National Council of Teachers of Mathematics (for The Mathematics Student), the Univ. of Waterloo (for the Ontario Secondary School Mathematics Bulletin), Kappa Mu Epsilon (for The Pentagon), the councillors of Pi Mu Epsilon (for The Pi Mu Epsilon Journal), the Society for Industrial and Applied Mathematics (for SIAM Review), School Science and Mathematics Association (for School Science and Mathematics), the editorial committee of Function, the Malaysian Mathematical Society (for Menemui Matematik), the Association of Mathematics Teachers of New York State (for The New York State Mathematics Teachers' Journal), the Ontario Association for Mathematics Education (for the Ontario Mathematics Gazette), the editor of Mathematical Spectrum, and Stickting Mathematisch Centrum (for Nieuw Archief voor Wiskunde). I also wish to thank the following people for their help in obtaining reprint permissions: Donald J. Albers, Ed Barbeau, Gerald E. Bergum, George Berzsenyi, Edwin Beschler, Jean T. Carpenter, Curtis Cooper, Michael Cornelius, R. G. Dunkley, Michael Ecker, Dale Ewen, Darrel W.

I am indebted to Donald Knuth who designed the Computer Modern family of typefaces used to print the mathematics in this book. The PostScript version of these fonts were built by Blue Sky Research. I am even more indebted to Donald Knuth for designing the TeX system for typesetting technical text which was used to typeset the mathematical portions of this book. I wish to thank Barry Smith and Blue Sky Research for their help and for creating TeXtures, which made editing this book a pleasure.
The following people and companies helped contribute to the success of MathPro Press:
David Barnes at CDL Mail Management, Anne Costa at ARC Enterprises, Tom D'Alessandro at Postal Center USA, Joan and Kathi Duprey at Ad Infinitum Graphic Services, Patricia Green at Copyland II, Kevin O'Reilly, Tom Plain at BookCrafters, Dan Poynter at Para Publishing, Judy Sawyer at Graphics Express of Carlisle, and Dianne Wires at BookMasters. I thank Alliant Computer Systems Corporation, Avid Technology, Inc., Digital Equipment Corporation, and Polybus Systems Corporation for their support in tolerating this venture.
The research could not have been completed without the cooperation of the many univ. libraries that open their doors to visiting mathematicians. I especially wish to acknowledge use of the libraries and research facilities at the following institutions:
Amherst College, Boston College, Brown Univ., Clark University, College of St. Rose, Colorado College, Columbia Univ., Courant Institute of Mathematical Sciences, Harvard Univ., Massachusetts Institute of Technology, North Carolina State Univ., Northeastern University, The Ohio State Univ., Smith College, Stanford University, State Univ. of New York at Albany, Tufts University, Union College, Univ. of California at Los Angeles, Univ. of Maine at Orono, University of Massachusetts at Amherst, Univ. of Nebraska at Lincoln, and Wake Forest University.
This book was produced using TeXtures, FullWrite Professional and FileMaker Pro running on an Apple Macintosh. The figures were drawn using Cabri-Géomètre and the Geometer's Sketchpad with occasional touch-up by SuperPaint. The cover was designed and composed by Kathi Duprey. Initial book design was by Paul Anagnostopoulos. The software for sorting problems and creating the indexes was written by Stanley Rabinowitz using THINK C. In addition to this custom software written especially for this project, the following commercial software was used during the production of this book:
Apple Macintosh operating system 6.0.7 and associated utilities, EdMetrics v0.5, Classic Textures v1.4 from Blue Sky Research, FullWrite Professional™ v1.5s from Ashton Tate, SuperPaint v2.0 from Silicon Beach Software, Inc., Adobe Type Manager® v2.0, Type Reunion™ v1.0, Font Downloader v4.14, Suitcase™ II v1.2.10 from Fifth Generations Systems, Inc., McSink™ v6.5 from Preferred Software, Inc., GCC Print Manager and driver v3.0.2 (with GCC Personal Laser Printer), Virus Detective® v4.0.4 by Jeffrey S. Shulman, FileMaker Pro 1.0v2 from Claris®, Cabri-géomètre v1.01 from Laboratoire Structures Discrètes et Didactique, Institut d'Informatique et de Mathématiques Appliqués de Grenoble, Geometer's Sketchpad v1.01 from Key Curriculum Press, and THINK C v5.0.1 from Symantec Corporation.
PostScript Fonts used: Computer Modern fonts (v1.0) from Blue Sky Research, Helvetica, Mathematical Pi and Cheq from Adobe. The PostScript Hebraica font used to print certain Hebrew alphametics was obtained from Linguist's Software, Inc., PO Box 580, Edmonds, WA 98020-0580 tel (206) 7751130. Bitmapped fonts used: msbm9 in AMSFonts v2.0 from the American Mathematical Society.
I wish to thank the many people who supplied details about unsolved problems and papers that reference problems:
Julia Abrahams, Petter Bjørstad, F. S. Cater, Peter Giblin, Doug Hensley, James Hirschfeld, Melvin Hochster, Kenneth R. Kellum, Armel Mercier, Thomas E. Moore, Harry Nelson, Joseph O'Rourke, David Singmaster, Lloyd N. Trefethen, and Peter Ungar.

Finally, I wish to thank all the problemists out there who have enriched my life and the lives of many others by contributing such fine problems to the mathematical literature. I hope they will understand the few cases where I have had to edit their creations in order to remove extraneous matter and fit the space constraints of this index. In particular, I must apologize to the Guayazuala Mathematical Society for ruling Professor Euclide Pasquale Bombasto Umbugio as incompetent, irrelevant, and immaterial. And, of course, a great thank you must go to all those problem column editors who endure a thankless task but provide an invaluable service to the mathematics community.
