证明了一维球指示函数的Fourier级数的逐点收敛性.每个维度的结果都大不相同。我们的证明方法依赖于格点问题,特别是捷克斯洛伐克数学家Betislav Novák的论文。
We prove the pointwise convergence of the Fourier series for the indicator function inddimensional ball. The results are very different for every dimension. Our method of proof depends on the lattice points problem, especially, on the papers of Czechoslovakian mathematician Břetislav Novák.
