A Study on Almost Matrix Summability of Fourier-jacobi Series
In this paper, a quite new theorem on almost summability of Fourier-Jacobi series has been established. Our theorem extends and generalizes all previously known results of this line of work. Full text
متن کاملSummability of a Class of Fourier-stieltjes Series
If 0 « (t)-)-s then, for any /3 > oc, Op (t)->-s. It is sufficient to assume that s = 0. By (3), since F(t) is increasing, op(t) <-a q « (t) and the required result follows immediately. t LEMMA 6. Let y(t) be an increasing function. If g(t) =10 y(u) du-sta as t-*0, then y(t)~sct a-1 The proof is similar to that of a result due to Hardy and Littlewood*, to which the lemma reduces when y(t) is a ...

and evaluating the generalized sum of (1) as the lim rm(x; f). The matrix ?2 will be subjected to the restrictions (i-iv) below. These restrictions are of such general nature, however, that they are satisfied by a great majority of the definitions of summability known in the literature. Our first condition on 21 is significant only in the case where 91 is of infinite reference. It is automatica...
متن کاملGeneralized matrix summability of a conjugate derived Fourier series
The study of infinite matrices is important in the theory of summability and in approximation. In particular, Toeplitz matrices or regular matrices and almost regular matrices have been very useful in this context. In this paper, we propose to use a more general matrix method to obtain necessary and sufficient conditions to sum the conjugate derived Fourier series.
متن کاملLogarithmic Summability of Fourier Series
A set of regular summations logarithmic methods is introduced. This set includes Riesz and Nörlund logarithmic methods as limit cases. The application to logarithmic summability of Fourier series of continuous and integrable functions are given. The kernels of these logarithmic methods for trigonometric system are estimated.
