Resumen de Soluciones cuasiperiódicas inestables en el problema de Poiseuille en dimensión 2
José Pablo Sánchez Casas, Àngel Jorba i Monte 
In the 2-D Poiseuille problem arise several Hopf bifurcations on the branch of secondary flows, which in turn bifurcate from the laminar solution. We analyze the first Hopf bifurcation of secondary flows where the period on time of the bifurcated solution is O(1000). Previous calculations of these solutions show that the Hopf bifurcation is subcritical and thus the bifurcated quasi-periodic solutions are locally stable. By improving the precision of the numerical approximation we obtain unstable quasi-periodic flows given rise to a supercritical Hopf bifurcation.
