文摘
The K λ-means were first introduced by Karamata. Vučković first studied the K λ-summability of a Fourier series and later on Lal studied the K λ-summability of a conjugate series. In the present paper, we have studied the |K λ|-summability of Fourier series and conjugate series. Mathematics Subject Classification 42A28
