报告题目:Multifractal analysis of non-uniformly contracting iterated function systems
报告摘要:Let $X = [0, 1]$. Given a non-uniformly contracting
conformal iterated function system (IFS) $\{ w_j \}_{j = 1}^m$ and a
family of positive Dini continuous potential functions $\{p_j\}_{j=1}^m$, the triple system $(X, \{w_j\}_{j=1}^m,\{p_j\}_{j=1}^m)$, under some conditions, determines uniquely a
probability invariant measure, denoted by $\mu$. In this talk, we discuss the pressure function of the system and multifractal structure of $\mu$. We prove that the pressure function is Gateaux differentiable and the multifractal formalism holds, if the IFS $\{ w_j \}_{j = 1}^m$ has non-overlapping.
