Multiplication Operators on Weighted Nakano (sss) [PDF]

open access: yesJournal of Mathematics, 2020
In this article, we investigate the sufficient conditions on weighted Nakano sequence space to be premodular Banach (sss). We examine some topological and geometrical structures of the multiplication operators defined on weighted Nakano prequasi-normed ...

Fixed Points of Kannan Maps in the Variable Exponent Sequence Spaces ℓp(·)

open access: yesMathematics, 2020
Kannan maps have inspired a branch of metric fixed point theory devoted to the extension of the classical Banach contraction principle. The study of these maps in modular vector spaces was attempted timidly and was not successful.

Ekeland Variational Principle in the Variable Exponent Sequence Spaces ℓp(·)

open access: yesMathematics, 2020
In this work , we investigate the modular version of the Ekeland variational principle (EVP) in the context of variable exponent sequence spaces ℓ p ( · ) . The core obstacle in the development of a modular version of the EVP is the failure

Some Fixed Point Results in Premodular Special Space of Sequences and Their Associated Pre-Quasi-Operator Ideal

open access: yesJournal of Function Spaces, 2021
A weighted Nakano sequence space and the s-numbers it contains are the subject of this article, which explains the concept of the pre-quasi-norm and its operator ideal. We show that both Kannan contraction and nonexpansive mappings acting on these spaces
