Last Update: Aug. 6, 2015
Here are most of my articles that were also published elsewhere. The Articles that were written after 1990 come with a "front" .html file, and are preprints. Those that were written prior to 1990 are .pdf files of scans of the published articles, kindly prepared by the brilliant young combinatorialist, Larry X. W. Wang, from Nankai University, who during my Nov. 2007 visit to Bill Chen's Combinatorics Kingdom, presented me with a beautifully prepared CD with most of my published articles.
Be sure to also look at The Personal Journal of Shalosh B. Ekhad and Doron Zeilberger, that contains papers that are exlusively published in this website.
Here is my CV, that includes the list of publications. (last update: May 18, 2012).
