Summa Summarum

"The ability to evaluate efficiently finite sums and combinatorial identities is a powerful tool for any mathematician or user of mathematics. As both a reference and an introduction to the art of manipulating sums for graduate and upper-level undergraduate students, researchers, and non-specialists, this book provides an array of systematic techniques that will help the reader to evaluate almost any finite algebraic sum."--BOOK JACKET.Larsen, Mogens Esrom is the author of 'Summa Summarum ', published 2007 under ISBN 9781568813233 and ISBN 1568813236.
