TRIP

Abstract

TRIP is an interactive computer algebra system that is devoted to perturbation series computations, and specially adapted to celestial mechanics. Its development started in 1988, as an upgrade of the special purpose FORTRAN routines elaborated by J. Laskar for the demonstration of the chaotic behavior of the Solar System. TRIP is now a mature and efficient tool for handling multivariate generalized power series, and contains also a numerical kernel. A limited version of TRIP is freely available on the WEB at www.imcce.fr/trip.
