| Research Abstract |
2009y : We obtained that for some transcendental entire functions,"the boundary of Siegel disks whose rotation number was of bounded type was a quasicircle". We obtained that the logarithmic lift of these transcendental entire functions had a wandering domain whose boundary was a quasicircle as a corollary.
2010y : We constructed some transcendental entire functions satisfying that "the boundary of Siegel disks whose rotation number was of bounded type was a quasicircle". We introduced a topology on the set of all entire functions respecting dynamics and we studied variation of Siegel disks for small perturbation with respect to the topology.
2011y : We comprehended the relationship between the qualitative theory of differential equations and complex dynamics, and we studied that(super) attracting periodic points, parabolic periodic points, Siegel points and Cremer points for complex dynamics and equilibrium points for differential equations.
