Citation Index for Neil Heffernan’s Tenure Package (Compiled June 2007- Last updated Sept 1, 2007)

In this citation index I have attempted to collect the references to my work that I happen to know of.  I filtered out papers where I was one of the authors.  This list has over 150 citations in total.  I have included URLs to the papers so you could see how they cited my work, but I am sure the URLs are liable to “break” over time so expect some broken links.
