Computer Algebra to bifurcation theory with symmetry. The classification of different bifurcation phenomena in case of several parameters is automated, based on a classification of Grobner bases of possible tangent spaces. The computations are performed in new coordinates of fundamental invariants and fundamental equivariants, with the induced weighted ordering. In order to justify the approach the theory of intrinsic modules is applied. Results for the groups D 3 ; Z 2 ; and Z 2 Theta Z 2 demonstrate that the algorithm works independent of the group and that new results are obtained. | Keywords | bifurcation theory, singularity theory, symmetry, systems
with several
parameters, Computer Algebra, Grobner bases |
