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 paper, we

study 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.
