This need appears in long time integrations (say, of the order of $10^9$ times some characteristic time of the system) and also for moderate time intervals when massive simulations are required for global and statistical purposes. Beyond classical methods there is at present a strong interest in ``geometric'' methods which are intended to preserve some geometric and/or structural properties of the system. It is worth to discuss the suitability of different methods as a function of the problem at hand. Furthermore moderate and long time integrations are used to detect properties (regularity, chaoticity) of the system which can be done by computing Lyapunov exponents and carrying out a frequency analysis. Another purpose is the numerical computation of relevant objects such as periodic and quasiperiodic solutions, etc, to study its stability, bifurcations and continuation as a function of parameters. These computations can require a very good accuracy. Finally, with methods having a very small truncation error, the role of the propagation of round off error should be studied, specially for regular (non-chaotic) orbits. Lecturers: G. Gomez (U.

For small and medium size computations different tools which can be used to obtain the desired results are available. However, faced to longer computations (e.g., dealing with a power series in 6 variables truncated to order 30, without any symmetry reduction, having near 2 million coefficients) they are useless. This lead to some scientists, mainly in Astronomy, to develop Algebraic Manipulators with specific purposes, for a concrete family of problems at the very beginning of the Computer Science. Since then a strong activity has been developed and programs able to deal efficiently with millions of terms have been produced. The first aim of the course is to present the basic concepts: data structure, basic and higher level operations, to use fully literal, rational or floating point (including multiple precision) coefficients and how to use them to be able to solve a variety of problems. The second aim is to encourage participants to write their own SAM to solve the problems in which they are interested, independently of the source of these problems. Problems in algebraic geometry have a lot in common with the analysis of singularities done in the study of differential equations and discrete transformations. The impact of new processor architectures and the possibility of distributed tasks will be also discussed. Lecturers: M. Gastineau (IMCCE, Observatoire de Paris), A. Giorgilli (U. di Milano), A.
