ON MEANS OF BANACH-SPACE-VALUED FUNCTIONS [PDF]
, 2012 We continue to study relations among exponential and polynomial growth orders of the γ-th order Cesàro means (γ≥0) and of the Abel mean for a Banach-space-valued function u on the interval [0,∞).

Matrix transformations of starshaped sequences
International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 4, Page 189-200, 2001., 2001 We deal with matrix transformations preserving the starshape of sequences. The main result gives the necessary and sufficient conditions for a lower triangular matrix A to preserve the starshape of sequences. Also, we discuss the nature of the mappings of starshaped sequences by some classical matrices.

International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 8, Page 533-538, 2000., 2000 We prove the necessary and sufficient conditions for an infinity matrix to be a mapping, from absolutely convergent series to convergent sequences, which is treated as general weighted mean summability methods. The results include a classical result by Hardy and another by Moricz and Rhoades as particular cases.

TAUBERIAN THEOREMS FOR THE WEIGHTED MEAN METHOD OF SUMMABILITY OF INTEGRALS [PDF]
, 2020 Let $q$ be a positive weight function on $\mathbf{R}_{+}:=[0, \infty)$ which is integrable in Lebesgue's sense over every finite interval $(0,x)$ for $00$, $Q(0)=0$ and $Q(x) \rightarrow \infty $ as $x \to \infty $.Given a real or complex-valued function

Approximation by double Walsh polynomials
International Journal of Mathematics and Mathematical Sciences, Volume 15, Issue 2, Page 209-220, 1992., 1992 We study the rate of approximation by rectangular partial sums, Cesàro means, and de la Vallée Poussin means of double Walsh‐Fourier series of a function in a homogeneous Banach space X. In particular, X may be Lp(I2), where 1≦p < ∞ and I2 = [0, 1) × [0, 1), or CW(I2), the latter being the collection of uniformly W‐continuous functions on I2. We extend

On deferred f-statistical convergence for double sequences
Open MathematicsIn 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-
