On superstability of exponential functional equations
Journal of Inequalities and Applications, 2021 The aim of this paper is to prove the superstability of the following functional equations: f ( P ( x , y ) ) = g ( x ) h ( y ) , f ( x + y ) = g ( x ) h ( y ) . $$\begin{aligned}& f \bigl(P(x,y) \bigr)= g(x)h(y), \\& f(x+y)=g(x)h(y). \end{aligned}$$

On superstability of derivations in Banach algebras
Open MathematicsIn this article, we consider some types of derivations in Banach algebras. In detail, we investigate the question of whether the superstability can be achieved under some conditions for some types of derivations, such as Jordan derivations, generalized ...

Superstability of derivations on Banach ∗-algebras
Advances in Difference Equations, 2017 In this paper, we show that approximate derivations on Banach ∗-algebras are exactly derivations and also show that approximate quadratic ∗-derivations on Banach ∗-algebras are exactly quadratic ∗-derivations by the fixed point theorem.

Superstability of functional equations related to spherical functions
Open Mathematics, 2017 In this paper we prove stability-type theorems for functional equations related to spherical functions. Our proofs are based on superstability-type methods and on the method of invariant means.

Some Comments on the Superstability of a General Functional Equation
SymmetryIn this paper, we prove a superstability theorem for a general functional equation ∑j=1∞ajf(γj(t,s))=h(t)g(s), with the unknown functions g:T→X, h:S→K and f:S→X, such that the series ∑j=1∞f(γj(t,s)) is convergent for every (s,t)∈S×T, where S and T are ...

Relative injective modules, superstability and noetherian categories [PDF]
Journal of Mathematical Logic, 2023 We study classes of modules closed under direct sums, $\mathcal{M}$-submodules and $\mathcal{M}$-epimorphic images where $\mathcal{M}$ is either the class of embeddings, $RD$-embeddings or pure embeddings. We show that the $\mathcal{M}$-injective modules

Superstability of the $ p $-power-radical functional equation related to sine function equation
Electronic Research Archive, 2023 In this paper, we find solutions and investigate the superstability bounded by a function (Gǎvruta sense) for the $ p $-power-radical functional equation related to sine function equation: \begin{document}$ \begin{equation*} f\left(\sqrt[p]{\frac{x ...
