Title: Boundaries of capture hyperbolic components
Time & Venue: 2024.09.02(星期一)9:30-11:30 S813
Abstract:A fundamental and challenging problem in complex dynamics is to study the topological structure of
high-dimensional hyperbolic component boundaries. In this talk, we discuss the capture hyperbolic components
in polynomial families defined by periodic critical relations. We show that the boundary of a capture
hyperbolic component is homeomorphic to a high-dimensional sphere. Moreover, we establish a
relation for Hausdorff dimensions between the parameter space and the dynamical space. This is a joint
work with Prof. Xiaoguang Wang and Prof. Yongcheng Yin.
Title: Boundaries of capture hyperbolic components
Time & Venue: 2024.09.04(星期三)9:30-11:30 S813
Abstract:In this talk, we discuss the central hyperbolic component of polynomials with a fixed critical point. We
will study the dynamical properties of polynomials on the central component boundary. By introducing the
chain of Fatou components, we can give a necessary but not sufficient condition for a polynomial belonging to the
central component boundary. This is an ongoing work with Prof. Xiaoguang Wang and Prof. Yon
