Abstract:
We study the bifurcation of the complex Arnold family f(z)=z+α+βsinz, where z is a complex variable, β is a small real parameter and the bifurcation is studied in the complex α-plane. One can see a structure called ``fingers'' or ``tentacles'' in the parameters space. (Also observed in Henon parameter space.) We study the qualitative and quantitative aspects of the fingers via parabolic bifurcation.
This is a work in progress joint with David Marti Pete (Kyoto University).
