P-completeness Theory
Luckily I had the opportunity to work with two great researchers writing a book on P-completeness: Jim Hoover and Larry Ruzzo. It was a long haul but we stuck it out and finished a challenging project.
Jim is maintaining a web site for the book. The site includes order informationand updates to the status of the open problems posed at the end of the book. The book is available from Oxford University Press at a very reasonable price (hey, it did take 10 years to write). Thanks Jim and Larry.
