Errata to Dominique Perrin and Antonio Restivo: Enumerative Combinatorics on Words, chapter in the "Handbook of Combinatorics". It has become more clear what are the essential topics, and many interesting new ancillary results have been discovered. Integer sequences and recursion: Quoting from elsewhere: Ronald L. Graham, Donald E. Knuth, Oren Patashnik, Concrete Mathematics, 2nd edition 1994 . The notes which became this book were for a course on Enumerative and Asymptotic Combinatorics at Queen Mary, University of London, in the spring of 2003. LaTeX sourcecode of the errata. The content is nearly identical to the 2004 release, save for a few typogr aphical corrections. homework. I found it very di cult but necessary to omit several beautiful, important directions.

The principles listed above are disarmingly simple and seemingly obvious. An addendum of new problems (and solutions) related to Catalan Wei). Solutions to Catalan number problems from previous link The five steps to EC enlightenment (Fan (with Sergey Shabanov) Concepts in Calculus Over the past few decades, Eulerian numbers have arisen in many interesting ways. Catalan addendum (Postscript or PDF) (version of 25 May 2013; 96 combinatorial interpretations Richard Stanley maintains a web site Information on Enumerative Combinatorics where this is explained better than I possibly can, and where the most recent errata and exercises can be downloaded. This method of determining f subsumes the previous two, as well as method 5, which follows.Any counting Change ci to c1.
