Many Body Tree Methods in Physics

MBTM front

A tutorial introduction to tree codes can be found in S. Pfalzner & P. Gibbon: "Many-Body Tree Methods in Physics" (also available as paperback). The book gives a description of the key features of the hierarchical tree method and discusses open boundary problems, as well as optimization of tree codes, periodic bounary problems, and the fast multipole method.

Further information, errata, and source code from the book can be found on Supplementary Material for "Many-Body Tree Methods in Physics" which is a replacement for the page http://www.astro.uni-koeln.de/~pfalzner/arboretum.html that is given in the book and are mirrored here for convenience.
