Rota-Baxter algebras and new combinatorial identities

Kurusch Ebrahimi-Fard, Jose M. Gracia-Bondia, Frederic Patras

Published 2006-12-31, updated 2007-01-11Version 2

The word problem for an arbitrary associative Rota-Baxter algebra is solved. This leads to a noncommutative generalization of the classical Spitzer identities. Links to other combinatorial aspects, particularly of interest in physics, are indicated.
