Mr-factors and Qr-factors for near quasinorm on certain sequence spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 2005 We study the multiplicativity factor and quadraticity factor for near quasinorm on certain sequence spaces of Maddox, namely, l(p) and l∞(p), where p=(pk) is a bounded sequence of positive real numbers.

Quasinormed spaces generated by a quasimodular
Journal of Inequalities and ApplicationsIn this paper, we introduce the notion of a quasimodular and we prove that the respective Minkowski functional of the unit quasimodular ball becomes a quasinorm.

Lebesgue's Differentiation Theorems in R.I. Quasi-Banach Spaces and Lorentz Spaces Γp,w [PDF]
Journal of Function Spaces and Applications, 2012 The paper is devoted to investigation of new Lebesgue's type differentiation theorems (LDT) in rearrangement invariant (r.i.) quasi-Banach spaces E and in particular on Lorentz spaces Γp,w={f:∫(f ...

Kannan Nonexpansive Operators on Variable Exponent Cesàro Sequence Space of Fuzzy Functions
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In general, we have constructed the operator ideal generated by extended s‐fuzzy numbers and a certain space of sequences of fuzzy numbers. An investigation into the conditions sufficient for variable exponent Cesàro sequence space of fuzzy functions furnished with the definite function to create pre‐quasi‐Banach and closed is carried out.

Kannan Nonexpansive Mappings on Nakano Sequence Space of Soft Reals with Some Applications
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We developed the operators ideal in this article by extending s‐soft reals and a particular space of sequences with soft real numbers. The criteria necessary for the Nakano sequence space of soft real numbers given with the definite function to be prequasi Banach and closed are investigated.

Some remarks concerning on a fuzzy real normed space [PDF]
, 2022 In mathematics, computer science, statistics, and other fields, the notion of fuzzy metric and fuzzy normed is crucial. Finding an acceptable fuzzy metric or norm for making some measurements can solve a lot of difficulties.

Fixed point theorems in generating spaces of quasi-norm family and applications
Fixed Point Theory and Applications, 2006 Some new concepts of generating spaces of quasi-norm family are introduced and their linear topological structures are studied. These spaces are not necessarily locally convex.

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We have defined and studied the weighted Nakano sequence spaces of fuzzy functions. We have constructed the ideal generated by extended s‐fuzzy functions and the sequence spaces of fuzzy functions. We present some topological and geometric structures of this class of ideal and multiplication mappings acting on this sequence space of fuzzy functions ...
