Bifurcation Diagram of Saddle/Spiral Bimodal Linear Systems
International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2017 We complete the study of the bifurcations of saddle/spiral bimodal linear systems, depending on the respective traces T and τ: one 2-codimensional bifurcation; four kinds of 1-codimensional bifurcations. We stratify the bifurcation set in the (T,τ)-plane

Extreme multiplicity in cylindrical Rayleigh-Bénard convection. II. Bifurcation diagram and symmetry classification. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2009 A large number of flows with distinctive patterns have been observed in experiments and simulations of Rayleigh-Bénard convection in a water-filled cylinder whose radius is twice the height. We have adapted a time-dependent pseudospectral code, first, to
