On Gradual Borel Summability Method of Rough Convergence of Triple Sequences of Beta Stancu Operators

open access: yesDera Natung Government College Research Journal, 2023
We define the concept of rough limit set of a triple sequence space of beta Stancu operators of Borel summability of gradual real numbers and obtain the relation between the set of rough limit and the extreme limit points of a triple sequence space of ...

On the summability of divergent power series solutions for certain first-order linear PDEs [PDF]

open access: yesOpuscula Mathematica, 2015
This article is concerned with the study of the Borel summability of divergent power series solutions for certain singular first-order linear partial differential equations of nilpotent type. Our main purpose is to obtain conditions which coefficients of

Analytic and summable solutions of inhomogeneous moment partial differential equations

open access: yes, 2016
We study the Cauchy problem for a general inhomogeneous linear moment partial differential equation of two complex variables with constant coefficients, where the inhomogeneity is given by the formal power series.

Comparison theorems for summability methods of sequences of fuzzy numbers

open access: yes, 2017
In this study we compare Ces\`{a}ro and Euler weighted mean methods of summability of sequences of fuzzy numbers with Abel and Borel power series methods of summability of sequences of fuzzy numbers. Also some results dealing with series of fuzzy numbers
