Approximation of Signals (Functions) by Trigonometric Polynomials in Lp-Norm

International Journal of Mathematics and Mathematical Sciences, 2014
Mittal and Rhoades (1999, 2000) and Mittal et al. (2011) have initiated a study of error estimates En(f) through trigonometric-Fourier approximation (tfa) for the situations in which the summability matrix T does not have monotone rows.

Wijsman ptrongly p-Cesàro summability and Wijsman statistical convergence of order α for double set sequences [PDF]

, 2019
The concept of statistical convergence was introduced by Steinhaus (1951) and Fast (1951), and later reintroduced by Schoenberg (1959) independently. Then, many researchers have studied on this concept until recently (see Connor 1988; Fridy 1985; Šalát ...

A Tauberian Theorem for Double Cesàro Summability Method

International Journal of Mathematics and Mathematical Sciences, 2016
We have generalized Littlewood Tauberian theorems for (C,k,r) summability of double sequences by using oscillating behavior and de la Vallée-Poussin mean.

On deferred f-statistical convergence for double sequences

Open Mathematics
In this article, we first put forward the concept of deferred f-double natural density for double sequences, where f is an unbounded modulus. Then, we combine f-density with deferred statistical convergence for double sequences and investigate deferred f-

Korovkin-Type Theorems for Positive Linear Operators Based on the Statistical Derivative of Deferred Cesàro Summability

Algorithms
In this paper, we introduce and investigate the concept of statistical derivatives within the framework of the deferred Cesàro summability technique, supported by illustrative examples.

On the mean summability by Cesaro method of Fourier trigonometric series in two-weighted setting

Journal of Inequalities and Applications, 2006
The Cesaro summability of trigonometric Fourier series is investigated in the weighted Lebesgue spaces in a two-weight case, for one and two dimensions.

A New Result on Generalized Absolute Cesàro Summability

International Journal of Analysis and Applications, 2016
In [4], a main theorem dealing with an application of almost increasing sequences, has been proved. In this paper, we have extended that theorem by using a general class of quasi power increasing sequences, which is a wider class of sequences, instead of

Some Tauberian conditions for the product of weighted and Cesáro summability methods for triple sequences

Revista Integración
In this paper, we show necessary and sufficient conditions under which convergence of a triple sequence in Pringsheim’s sense follows from its weighted-Cesáro summability. These Tauberian conditions are one-sided or two sided if it is a sequence of real
