报告题目(一): On the largest partial quotient and uniform Diophantine approximation

报告人:余月力 副教授(武汉大学)

摘要We consider the sets of $x$ defined by some growth rate of the largest partial quotient in the continued fraction expansions of $x$. This set can also be defined by a uniform Diophantine approximation of the Gauss map. We extend some known results about the uniform approximation of the beta transformation.

报告题目(二)Multiplicity of topological dynamical systems

报告人:史汝西 博士(法国索邦大学)

摘要For a topological dynamical system, we introduce the concept of topological multiplicity. In this talk, I will present its definition and several properties of topological systems with finite multiplicity. I will also discuss several examples to illustrate this concept. If time permits, I will talk about the multiplicity of subshifts with linear growth complexity. Some open problems related to this topic will be discussed during the talk. This is a joint work with David Burguet.
