Computer Algebra for Dynamical Systems and Celestial Mechanics

at ACA'2008 to be held at RISC, Linz, Austria (July 27-30)

Session Organizers:

Overview:

Celestial Mechanics and Dynamical Systems are traditional fields for applications of computer algebra. This session is intended to discuss Computer Algebra methods and modern algorithms in the study of general continuous and discrete Dynamical Systems, Ordinary Differential Equations and Celestial Mechanics.

The following topics, among others, will be considered:

Stability and bifurcation analysis of dynamical systems

Construction and analysis of the structure of integral manifolds

Symplectic methods.

Symbolic dynamics.

Normal forms and programs for their computations.

Deterministic chaos in dynamical systems.

Families of periodic solutions.

Perturbation theories.

Exact solutions and partial integrals.

Analysis of singularities of equations by power geometry algorithms.

Computation of asymptotic forms and asymptotic expansions of solutions and its program implementation.

Integrability and nonintegrability of ODEs.

Computation of formal integrals.

Computer algebra for celestial mechanics and stellar dynamics.

Specialized computer algebra software for celestial mechanics.

Topological structure of phase portraits and computer visualization.
