Abstract

We obtain an estimate for the convergence rate of the Fourier series of a continuous periodic function in terms of the modulus of continuity of the function and the value of its \(p\)-variation. We prove that the leading term of the estimate is sharp.

有界 $$p$$ 变量的连续周期函数的傅里叶级数均匀收敛率估计
摘要 我们根据连续周期函数的连续性模量及其 \(p\)- 变量的值,得到了连续周期函数傅里叶级数收敛率的估计值。我们证明了该估计的前导项是尖锐的。
