AI 中文摘要
我们证明,对于一个$C^r$通用表面排斥子($1 < r \leq \infty$),其Hausdorff维数与盒维数恰好是次可加拓扑压力函数的唯一零点。作为该框架的应用,我们表明满足强分离条件(SSC)的一致非共形且弱不可约的平面非线性迭代函数系统(IFS)的吸引子达到其预期的Hausdorff维数与盒维数。此外,作为通用排斥子定理的直接推论,我们推导出该维数公式对满足SSC的通用$C^r$平面IFS也成立。利用该方法,我们还推广了Ren和Shen(2021)关于Weierstrass型函数图像的二分结果,将其实解析要求弱化至$r > 1$时的任意$C^r$正则性。
英文摘要
We establish that for a $C^r$-generic surface repeller ($1 < r \leq \infty$), its Hausdorff and box dimensions are exactly the unique zero of the sub-additive topological pressure function. As an application of our framework, we show that the attractor of a uniformly non-conformal and weakly irreducible planar non-linear iterated function system (IFS) satisfying the strong separation condition (SSC) attains its expected Hausdorff and box dimensions. Furthermore, as a direct consequence of our generic repeller theorem, we deduce that this dimension formula also holds for a generic $C^r$ planar IFS satisfying the SSC. Using this approach, we also extend the dichotomy result for graphs of Weierstrass-type functions of Ren and Shen (2021) by weakening their real-analytic requirement to arbitrary $C^r$ regularity for $r > 1$.
