摘要:
In this talk, we introduce several results on the topology and geometry of the boundaries of hyperbolic components of
cubic polynomials in the slice S_p in which the polynomial has a periodic critical point of period p. It is showed
that the boundary of a capture component in S_1 is a quasicircle. For p>=2, it is proved that for a special unbounded
hyperbolic component in S_p, there is an embedded image of a relevant cut-open quadratic Julia set on it boundary.
