The stability of high ring homomorphisms and derivations on fuzzy Banach algebras

Open Mathematics
In this article, we focus on exploring the fuzzy version of the Hyers-Ulam-Rassias stability of nn-ring homomorphisms and nn-ring derivations in the context of fuzzy Banach algebras. Our investigation utilizes the direct method.

Almost periodic solutions of Volterra difference systems

Demonstratio Mathematica, 2017
We study the existence of an almost periodic solution of discrete Volterra systems by means of fixed point theory. Using discrete variant of exponential dichotomy, we provide sufficient conditions for the existence of an almost periodic solution.

On Transcendental Entire Solution of Fermat-Type Trinomial and Binomial Equations Under Restricted Hyper-Order

Annales Mathematicae Silesianae
In this paper we are focusing on finding the transcendental entire solution of Fermat-type trinomial and binomial equations, by restricting the hyper-order to be less than one.

Kallman-Rota type inequality for discrete evolution families of bounded linear operators

, 2017
Let X be a complex Banach space and Z+ be the set of all nonnegative integers. Let K00(Z+,X ) be the space of all X -valued bounded sequences which decays to zero at 0 and at ∞ .
