Analytic differenceability of functions
Volume 3, Issue 1 , February 2021, Pages 1-12
Abstract
Analytic summability of functions was introduced by Hooshmand in 2016. He used Bernoulli numbers and polynomials Bn(z) to define analytic summability and related analytic summand functions. ... Read More
Generalized Ulam-Hyers stability of an alternate additive-quadratic-quartic functional equation in fuzzy Banach spaces
Volume 3, Issue 1 , February 2021, Pages 13-31
Abstract
In this paper, we obtain and establish the generalized Ulam-Hyers stability of an additive-quadratic-quartic functional equation in fuzzy Banach spaces. Read More
Some results on disjointness preserving Fredholm operators between certain Banach function algebras
Volume 3, Issue 1 , February 2021, Pages 32-39
Abstract
For two algebras $\A$ and $\B$, a linear map $T : \A \lo \B$ is disjointness preserving if $x \cdot y = 0$ implies $Tx \cdot Ty = 0$ for all $x, y \in \A$ and is said ... Read More
Weakly principally quasi-Baer rings and generalized triangular matrix rings
Volume 3, Issue 1 , February 2021, Pages 39-45
Abstract
A ring $R$ is called weakly principally quasi-Baer or simply (weakly p.q.-Baer) if the right annihilator of a principal right ideal is right $s$-unital by right semicentral ... Read More
A proof of the Cauchy--Schwarz inequality from the change of reference frame
Volume 3, Issue 1 , February 2021, Pages 46-47
Abstract
Inspired by [1] a proof of the Cauchy--Schwarz inequality is given by considering the transformation between two different inertial reference frames. Read More
