告摘要:

Takagi'sfunction is a continuous nowhere-differentiable function constructedby Takagi in 1903. In this paper, we study the local level sets ofTakagi's function. By using the tools of Moran sets and symbolicspaces, we establish the Hausdorff dimension of local level sets for$x\in[0,1]$ and obtain the range of the Hausdorff dimension. Inaddition, we derive a lower bound for the Hausdorff dimension of theset of points $x$ whose local level set has Hausdorff dimension $s$.
