Description

Computer algebra techniques/softwares have been used in theoretical/computational physics (such as general relativity, quantum physics, solid state physics, etc) since the late sixties. Nowadays, due to dramatic improvements in hardware, algorithms and software systems, more and more non-trivial results, e.g. in perturbation theory and stability theory in PDE, are achieved by using computer algebraic methods/programs. While for physicists the results and the interpretation of their research is naturally most important, it is realized at a larger scale now that computer algebra systems and special-purpose programs written in the corresponding mathematical high-level languages can be extremely useful (and fun) when doing calculationally intensive investigations. This session has as its goal to bring together researchers who make serious use of computer algebra theory/systems in theorical or computational physics.
