后向连分数映射的李雅普诺夫指数的多重分形分析

Multifractal analysis of Lyapunov exponent for the backward continued fraction map

Godofredo Iommi

摘要:

本文研究了具有无穷多个分支和抛物不动点的区间映射的李雅普诺夫指数的重分形谱。事实证明,在强烈对比的双曲的情况下,域的频谱是无界的,不可微的点可能存在。此外,光谱不是凹的。我们建立了确保拐点存在的条件。我们还研究了这种映射的热力学形式。我们证明了压力函数在一定区间内是实解析的,然后它就等于零。

英文摘要:

In this note we study the multifractal spectrum of Lyapunov exponents for interval maps with infinitely many branches and a parabolic fixed point. It turns out that, in strong contrast with the hyperbolic case, the domain of the spectrum is unbounded and points of non-differentiability might exist. Moreover, the spectrum is not concave. We establish conditions that ensure the existence of inflection points. We also study the thermodynamic formalism for such maps. We prove that the pressure function is real analytic in a certain interval and then it becomes equal to zero.
