| In this paper, we discuss Fourier-Denjoy series. We first prove some convergence theorems in a new way. And this method of proof may be understood easily.Secondly, we discuss several typical properties of Fourier-Denjoy series. Then we obtain a nice property of the partial sum of Fourier-Denjoy, which dissatisfied Riemann-Lebesgue lemma.Finally, we discuss anomalous integral, which play a important role of Fourier-Denjoy series. |
