多项式傅里叶级数的多重分形行为
Multifractal behavior of polynomial Fourier series
摘要:
我们证明了多项式频率的傅里叶级数的“奇异谱”的非平凡上、下界。函数f的奇点谱给出了具有给定霍德尔指数的点集的豪斯多夫维数。
英文摘要:
We prove non-trivial upper and lower bounds for the "Spectrum of Singularities" of Fourier Series with polynomial frequencies. The Spectrum of Singularities of a function f gives the Hausdorff dimension of the set of points with a given Hölder exponent for f.
