报告题目：Regularity of bounded critical Fatou components for polynomials.
摘要：Let $U$ be a bounded critical Fatou component for a polynomial.
(1). If $U$ is attracting and its boundary contains neither parabolic points nor recurrent critical points, then $U$ is a quasidisk.
(2). If $U$ is parabolic associate with a paraboloc point $p$ and $\partial U\{p}$ contains neither parabolic points nor recurrent critical points, then $U$ is a John domain. Moreover, if there are at least two petals, then $U$ is a quasidisk.
