关于MVBV条件下Fourier级数的L^1收敛性的注记(英文)

A Remark on L^1-convergence of Fourier Series Under MVBV Condition

本注记给出了关于在Fourier级数L^1收敛中MVBV条件不可减弱的一个猜想的肯定回答。

This note is to give a conjecture which claims that the MVBV condition is also the weakest condition one can have to replace the monotone condition in L^1 convergence case,an affirmative answer.
