摘 要：In the famous work by Buff and Cheritat constructing quadratic Julia sets with positive area, the control of the shape of perturbed Siegel disks is a key technique. To do it, Buff and Cheritat added a restrictive condition on rotation numbers. Recently, Professor Jianyong Qiao and I showed that this restrictive condition can be deleted. As a byproduct, we can get more quadratic Julia sets with positive area than the original result by Buff and Cheritat. In this talk, I will give a report on this result.
