dc.description.abstract |
Since the publication in 2000 of the completely reset sixth edition of Gradshteyn and Ryzhik, users of the
reference work have continued to submit corrections, new results that extend the work, and suggestions
for changes that improve the presentation of existing entries. It is a matter of regret to us that the
structure of the book makes it impossible to acknowledge these individual contributions, so, as usual,
the names of the many new contributors have been added to the acknowledgment list at the front of the
book.
This seventh edition contains the corrections received since the publication of the sixth edition in
2000, together with a considerable amount of new material acquired from isolated sources. Following
our previous conventions, an amended entry has a superscript “11” added to its entry reference number,
where the equivalent superscript number for the sixth edition was “10.” Similarly, an asterisk on an
entry’s reference number indicates a new result. When, for technical reasons, an entry in a previous
edition has been removed, to preserve the continuity of numbering between the new and older editions
the subsequent entries have not been renumbered, so the numbering will jump.
We wish to express our gratitude to all who have been in contact with us with the object of improving
and extending the book, and we want to give special thanks to Dr. Victor H. Moll for his interest in
the book and for the many contributions he has made over an extended period of time. We also wish to
acknowledge the contributions made by Dr. Francis J. O’Brien Jr. of the Naval Station in Newport, in
particular for results involving integrands where exponentials are combined with algebraic functions.
Experience over many years has shown that each new edition of Gradshteyn and Ryzhik generates
a fresh supply of suggestions for new entries, and for the improvement of the presentation of existing
entries and errata. In view of this, we do not expect this new edition to be free from errors, so all
users of this reference work who identify errors, or who wish to propose new entries, are invited to
contact the authors, whose email addresses are listed below. Corrections will be posted on the web site |
