Olver</a></h4><h4>Last updated:   October 29, 2014</h4>In 1999, I started posting a set of <a href="http://www-users.math.umn.edu/~olver/appl.html" target="_blank">Lecture Notes on Applied Mathematics</a> on my <a href="http://www-users.math.umn.edu/~olver/index.html" target="_blank">web site</a>. A subset of these notes became an undergraduate text on <a href="http://www-users.math.umn.edu/~olver/ala.html" target="_blank">Applied Linear Algebra</a>, co-authored with my wife, <a href="http://courseweb.stthomas.edu/cshakiban/" target="_blank">Cheri Shakiban</a>, which was published in 2006 by <a href="http://vig.prenhall.com/" target="_blank">Prentice-Hall</a>. Another subset became a second undergraduate textbook, <a href="http://www-users.math.umn.edu/~olver/pde.html" target="_blank">Introduction to Partial Differential Equations</a>, which was published in 2014 by <a href="http://www.springer.com/" target="_blank">Springer</a>.In 2006, both <a href="http://www.alphasci.com/" target="_blank">Alpha Science International</a>, a publisher based in Oxford, UK, and <a href="http://www.narosa.com/" target="_blank">Narosa Publishing House</a>, based in India, published a book, entitled Complex Analysis with Vector Calculus, by T.M.J.A. Cooray, a mathematician employed by the <a href="http://www.mrt.ac.lk/" target="_blank">University of Moratuwa</a>, in Sri Lanka. I was completely unaware of this book at that time.In November, 2009, I received an email from <a href="http://ramanujan.math.trinity.edu/wtrench" target="_blank">William Trench</a>, the Andrew G. Cowles Distinguished Professor Emeritus of Mathematics at <a href="http://web.trinity.edu/" target="_blank">Trinity University</a>, alerting me to the fact that Mr. Cooray was in the process of plagiarizing material from Trench's text <a href="http://ramanujan.math.trinity.edu/wtrench/misc/index.shtml" target="_blank">Introduction to Real Analysis</a> for a forthcoming book on Engineering Mathematics with the same publishers. In addition, he wrote that Cooray's Complex Analysis with Vector Calculus book was in large part plagiarized from my <a href="http://www-users.math.umn.edu/~olver/appl.html" target="_blank">Lecture Notes</a> and an online text on <a href="http://people.math.gatech.edu/~cain/winter99/complex.html" target="_blank">Complex Analysis</a>, first posted in 1999, by <a href="http://people.math.gatech.edu/~cain/" target="_blank">George Cain</a>, a Professor of Mathematics at <a href="http://www.gatech.edu/" target="_blank">Georgia Tech</a>. Examination of excerpts from Cooray's book confirmed the charges — large sections of his text were copied verbatim from the 2005 version of my notes. (Earlier versions of my notes, going back to 1999, can be found using the <a href="http://www.archive.org/" target="_blank">Wayback Machine</a>.) Neither of us was contacted by Mr. Cooray nor the publishers, either before or following publication of the book, nor was any permission to copy our copyrighted work implied or given to them.A short example of the plagiarized material can be found <a href="http://www-users.math.umn.edu/~olver/plag.html#1" target="_blank">below</a>. The plariarized text runs to many pages. See also George Cain's <a href="http://hausdorff.net/theft/" target="_blank">web page</a> devoted to this matter. The latest version of my lecture notes on Complex Analysis and Conformal Mapping can be found <a href="http://www-users.math.umn.edu/~olver/ln_/cml.pdf" target="_blank">here</a>Acting on this situation, I retained <a href="http://www.forsythsimpson.com/" target="_blank">Forsyth Simpson</a>, an intellectual property law firm based in London, UK. Following our presentation of the evidence, Alpha Science and Narosa quickly admitted that Cooray's work was indeed plagiarized. They then agreed to cease sales, destroy all copies, and pay damages and legal fees. A copy of their letter can be found <a href="http://www-users.math.umn.edu/~olver/book_/plet.pdf" target="_blank">here</a>. Since then, I <a href="http://www-users.math.umn.edu/~olver/book_/mlet.pdf" target="_blank">wrote</a> to the administration of the <a href="http://www.mrt.ac.lk/" target="_blank">University of Moratuwa</a>, and they subsequently responded that they were conducting their own investigation into this matter. However, despite further correspondence with them over the next couple of years, as of October 29, 2014, Mr. Cooray is apparently still employed by the University of Moratuwa.Plagiarism is, unfortunately, becoming an increasingly common problem in modern scientific research. An eye-opening and disturbing description of cases involving the <a href="http://www.siam.org/" target="_blank">Society for Industrial and Applied Mathematics (SIAM)</a> can be found in an <a href="http://ima.umn.edu/~arnold/siam-columns/integrity-under-attack.pdf" target="_blank">editorial</a> written by my colleague, <a href="http://ima.umn.edu/~arnold/" target="_blank">Doug Arnold</a>, current President of SIAM, that appears in the December, 2009 issue of <a href="http://www.siam.org/news/" target="_blank">SIAM News</a>.------ Post added on [DATETIME="UT"]1622700283[/DATETIME]</blockquote>
