Analogues of some Tauberian theorems for stretchings
International Journal of Mathematics and Mathematical Sciences, 2001 We investigate the effect of four-dimensional matrix transformation on new classes of double sequences. Stretchings of a double sequence is defined, and this definition is used to present a four-dimensional analogue of D.

$L^p$-integrability, dimensions of supports of fourier transforms and applications
, 2014 It is proved that there does not exist any non zero function in $L^p(\R^n)$ with $1\leq p\leq 2n/\alpha$ if its Fourier transform is supported by a set of finite packing $\alpha$-measure where ...

Approximation of the semi-infinite interval
International Journal of Mathematics and Mathematical Sciences, 1980 The approximation of a function f∈C[a,b] by Bernstein polynomials is well-known. It is based on the binomial distribution. O. Szasz has shown that there are analogous approximations on the interval [0,∞) based on the Poisson distribution.

Some Tauberian theorems for Euler and Borel summability
International Journal of Mathematics and Mathematical Sciences, 1980 The well-known summability methods of Euler and Borel are studied as mappings from ℓ1 into ℓ1. In this ℓ−ℓ setting, the following Tauberian results are proved: if x is a sequence that is mapped into ℓ1 by the Euler-Knopp method Er with r>0 (or the Borel ...

Analytic combinatorics for a certain well-ordered class of iterated exponential terms [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 The aim of this paper is threefold: firstly, to explain a certain segment of ordinals in terms which are familiar to the analytic combinatorics community, secondly to state a great many of associated problems on resulting count functions and thirdly, to ...

A uniform Tauberian theorem in optimal control [PDF]
, 2010 In an optimal control framework, we consider the value $V_T(x)$ of the problem starting from state $x$ with finite horizon $T$, as well as the value $V_\lambda(x)$ of the $\lambda$-discounted problem starting from $x$.

Tauberian theorems for statistical convergence
Tamkang Journal of Mathematics, 2017 The Tauberian theorems for statistical limitable method are proved by both Fridy and Khan \cite{3} and M\'oricz \cite{28}. Here we generalize these theorems to (C; i) statistical limitable method.
