PDC-seminarium: Global bifurcations on a surface reaction catalysis model

Martin Zimmerman, Uppsala, håller ett seminarium under ovanstående rubrik på tisdag (12 mars) kl. 15.15 i seminarierum 1537 (Lindstedtsv. 3, plan 5).

Abstract

After an introduction to partial differential equations applied to chemistry (reaction-diffusion PDE's), I will introduce a model to surface reaction catalysis on a Pt surface. We have analyzed this system with tools from the theory of non-linear dynamics. In particular we investigated the so-called traveling-wave ODE (ordinary differential equation) and found several global bifurcations. One of them is responsible of a dramatic change on the attractor of the PDE, giving rise to spatio-temporal complex behavior. The other global bifurcation is seen qualitatively as the driving force of the latter complex behavior.
