Kocean:傅里叶级数(Fourier Series)42 赞同 · 2 评论文章 复数傅里叶级数如下所示 f(t)=∑n=−∞n=∞Cneinωt 其中,Cn=1T∫−T/2T/2f(t)e−inωtdt 假设当周期T变得无穷大时,基频(Fundamental Frequency)ω会变得很小,因此变成dω。为了得到任意有限的频率ω,n需要趋向于无穷。因此ndω→ω,所...
pointwise convergence of fourier series级数逐点收敛.pdf,Preface This book grew out of my attempt in August 1998 to compare Carleson’s and Fefferman’s proofs of the pointwise convergence of Fourier series with Lacey and Thiele’s proof of the boundedn
